🌐 1. Global Trade Turmoil Intensifies Amid U.S. Tariffs
The U.S. administration’s sweeping tariff policy is causing substantial disruptions in the global supply chain, with experts warning that the worst may be yet to come. Following the implementation of a 10% baseline tariff globally and a 145% tariff on Chinese imports, freight booking volumes have plummeted, with U.S. imports from China down 36%. Stockpiling efforts by businesses have temporarily shielded consumers, but inventories are depleting, and new orders are on hold awaiting a resolution. This is likely to lead to empty shelves and price hikes beginning as early as May or June, with particularly sharp impacts on low-margin consumer goods.

Like Heinlein’s Athena, my AI is sharp, loyal, and just a little too clever for everyone’s comfort.
A while back I wrote a post about Tim Berners-Lee, the inventor of the World Wide Web, and his vision of a transformative shift in the way individuals manage and share their personal data through a decentralized web, embodied by his Solid project. For me, a natural extension of this thinking is to continue the trend of decentralization and move the control of our digital world to individual households.
In a future where every household has its own independent AI system, life would undergo a profound transformation. These AI systems, acting as personal assistants and home managers, would prioritize privacy, efficiency, and user control. Unlike AI tethered to large platforms like Meta or Google, these systems would function autonomously, severing reliance on centralized data mining and ad-driven business models.
Each household AI could be a custom-tailored entity, adapting to the unique needs of its users. It would manage mundane tasks like cooking, cleaning, and maintaining the home while optimizing energy use and sustainability. For example, the AI could monitor household appliances, automatically ordering repairs or replacements when necessary. It could manage grocery inventory and nutritional needs, preparing healthy meal plans tailored to individual dietary requirements. With integration into new multimodal AI models that can process video, audio, and sensor data simultaneously, these systems could actively respond to real-world inputs in real time, making automation even more fluid and responsive.
Beyond home management, the AI would act as a personal assistant to each household member. It could coordinate schedules, manage communication, and provide reminders. For students, it might assist with personalized learning, adapting teaching methods to their preferred style using cutting-edge generative tutoring systems. For professionals, it could optimize productivity, handling email correspondence, summarizing complex reports, and preparing interactive visualizations for meetings. Its ability to understand context, emotion, and intention, now part of the latest frontier in AI interaction design, would make it feel less like a tool and more like a collaborator.
A significant feature of these AIs would be their robust privacy measures. They would be designed to shield households from external intrusions, such as unwanted adverts, spam calls, and data-harvesting tactics. Acting as a filter between the household and the digital world, the AI could block intrusive marketing efforts, preserving the sanctity of the home environment. The adoption of on-device processing, federated learning, and confidential computing technologies has already made it possible to train and run large models without transmitting sensitive data to external servers. This would empower users, giving them control over how their data is shared, or not shared, on the internet.
The independence of these AI systems from corporations like Meta and Google would ensure they are not incentivized to exploit user data for profit. Instead, they could operate on open-source platforms or subscription-based models, giving users complete transparency and ownership of their data. Developments in decentralized AI networks, using technologies like blockchain and encrypted peer-to-peer protocols, now make it feasible for these household systems to cooperate, share models, and learn collectively without exposing individual data. These AIs would communicate with external services only on the user’s terms, allowing interactions to remain purposeful and secure.
However, challenges would arise with such autonomy. Ensuring interoperability between household AIs and external systems, such as smart city infrastructure, healthcare networks, or educational platforms, without compromising privacy would be complex. AI alignment, fairness, and bias mitigation remain open challenges in the industry, and embedding strong values in autonomous agents is still a frontier of active research. Additionally, the potential for inequality could increase; households that cannot afford advanced AI systems might be left behind, widening the technological divide.
In this speculative future, household AI would shift the balance of power from corporations to individuals, enabling a world where technology serves people rather than exploits them. With enhanced privacy, personalized support, and seamless integration into daily life, these AIs could redefine the concept of home and human agency in the digital age. The key would be to ensure that these systems remain tools for empowerment, not control, embodying the values of transparency, autonomy, and fairness.
Here’s the inaugural edition of my new weekly segment, “Five Things We Learned This Week,” highlighting significant global events and discoveries from April 12–18, 2025.

If time were to happen all at once – where past, present, and future coexisted simultaneously – it would upend our understanding of reality, causality, and even consciousness itself. Our perception of time as a flowing sequence of events is deeply ingrained in both our experience and our scientific models, but what if that flow was an illusion? What if every moment simply existed, with no distinction between before and after?
One of the most immediate consequences of such a reality would be the breakdown of cause and effect. Our world operates on the principle that actions have consequences, that the past influences the present, which in turn shapes the future. If time were simultaneous, there would be no before or after – everything would simply be. In such a reality, would it even make sense to speak of events “happening”? Without sequence, there is no causality, and without causality, the entire structure of our decision-making and agency becomes questionable. Could free will exist in a reality where all choices have already unfolded in every possible way?
Our perception of time is not just a philosophical construct, but a deeply embedded feature of human consciousness. We process the world sequentially because our brains are wired to do so. If time were happening all at once, would we experience our entire lives simultaneously? Would we be both a newborn and an elderly person at the same time, fully aware of every moment we have ever lived? If that were the case, then identity itself might become meaningless, dissolving into an incomprehensible blur of every possible experience. Alternatively, it is possible that our consciousness would still only access one “slice” at a time, navigating an eternal landscape without truly perceiving its timeless nature.
This idea is not entirely foreign to physics. The “block universe” model in relativity suggests that time is a fixed, four-dimensional structure where the past, present, and future all exist equally. In this view, time does not “flow”; rather, it is a static dimension much like space, with our perception of movement through it being an emergent phenomenon. If this were true, the notion of “now” would be subjective, merely a point of reference chosen by an observer rather than a fundamental feature of the universe. This model sounds similar to how the fictional wormhole aliens in Star Trek: Deep Space 9 live, as they have no understanding of linear time, and the concept of consequences.
Another major implication of a timeless reality is how it would affect the laws of physics themselves. Much of modern science relies on the assumption that time allows for entropy, the increase of disorder in a system. This principle explains why we remember the past but not the future and why systems evolve rather than remaining frozen in place. If time did not progress, but instead existed as a complete whole, then entropy might be an illusion, or at the very least, an incomplete way of understanding change. Could it be that what we perceive as time’s passage is simply our consciousness moving through an already-existent structure?
If time truly happened all at once, it would redefine the very nature of reality. Perhaps we are already living in such a universe but are unable to perceive its full nature due to the limitations of human cognition. What we call “the present” might just be a thin veil over a vast, timeless structure, one that we are only beginning to understand.
In recent years, artificial intelligence has made its mark on many industries, from healthcare to finance, but one of the most striking developments is its encroachment on the world of creative writing. As AI systems like ChatGPT become more advanced, the boundaries between human and machine-generated content blur. We’re left wondering, are we witnessing the dawn of a new creative era, or are we simply setting ourselves up for an intellectual shortcut that could undermine the craft of storytelling?
The impact of AI on literature, journalism, and speculative fiction is already apparent. Authors are using AI as a tool to assist with everything from generating ideas to drafting full-length novels. While this opens up exciting possibilities for writers who may struggle with writer’s block, it also raises a host of questions about authenticity. Can a machine, devoid of lived experience, truly capture the nuances of human emotion or the subtleties of cultural context? AI may be adept at mimicking patterns of language, but does it understand the story it tells? And even more importantly, does it feel the story?
Journalism, a field traditionally built on human insight and investigative rigor, is also seeing a dramatic shift. AI-driven tools can now write articles with stunning speed, churning out copy on everything from politics to sports. The convenience is undeniable. Newsrooms, under pressure from tight deadlines and dwindling resources, find AI a helpful ally in meeting the demand for continuous content. But there’s a worrying undercurrent here: Can we trust a machine to provide the nuanced, ethical, and context-rich reporting that we need in an increasingly complex world? The thought of an algorithm determining what’s “newsworthy” is chilling, particularly when considering how data-driven models often fail to detect or represent bias, or how they may inadvertently amplify misinformation.
Perhaps the most exciting, and also the most concerning, role AI is playing is in speculative fiction. Writers have long used the genre to explore what might happen in the future, and with AI capable of generating entire worlds and characters in minutes, the scope for innovation is limitless. But there’s a risk that AI-generated speculative fiction will end up being more formulaic than fantastic. If every story is based on pre-existing patterns or data sets, will we lose the very essence of speculative fiction – the wild, unexpected ideas that challenge our assumptions about the world? The creative chaos that makes the genre so thrilling could give way to an artificial predictability that lacks true human imagination.
At the heart of these concerns is the broader issue of creativity itself. Writing, like all art, is a deeply personal expression. It reflects the writer’s experiences, their worldview, their struggles. Can an AI, which operates purely on patterns and algorithms, truly replicate this? Even if it can produce a perfectly structured story, does it have the soul that comes from a human hand? There is something to be said for the imperfections in art – the missed commas, the stray metaphors, the oddities that make it feel real. AI, by its very nature, smooths out those edges.
At this point I should perhaps clarify my own use of AI tools. I am a storyteller by nature, and this blog is only one of many creative outlets. I tend to use AI in a consistent manner – for researching a topic when I feel I need more information, and then to edit my first rough draft. I always edit/rewrite my published work as I find AI to have questionable grammar and horrible punctuation. If this changes, I will write a piece about it, and mention my new process in the About section.
So, as we hurtle toward this AI-infused future, we must ask ourselves, what is the value of a story? Is it the perfect sentence, the perfect insight, or is it the unique perspective of the person telling it? AI is undoubtedly changing the landscape of creative writing, but whether it enriches or diminishes the craft remains to be seen. As writers, readers, and cultural observers, it’s essential that we hold onto the human essence of storytelling – because once we lose that, we may never get it back.
Mount Paektu, also known as Changbai Mountain in China, is an awe-inspiring stratovolcano straddling the border between North Korea and China. Towering at 2,744 meters (9,003 feet), it is the highest peak on the Korean Peninsula and holds profound cultural and historical significance. Revered in Korean and Manchu mythology, it is considered the mythical birthplace of the Korean people and an important symbol of national identity. However, beyond its legendary status lies a geological powerhouse with a history of catastrophic eruptions, the most infamous of which – known as the Millennium Eruption – ranks among the most extreme volcanic events of the past two millennia.
The Millennium Eruption of 946 CE was a cataclysmic event that ejected an estimated 100 cubic kilometers of pyroclastic material into the atmosphere. The eruption is thought to have been comparable in magnitude to the 1815 Tambora eruption, which triggered a global “year without a summer.” Ash from Paektu has been discovered in sediment cores as far away as Japan and even Greenland, underscoring the immense dispersal of volcanic material. This eruption reshaped the summit, forming the massive crater that now cradles Heaven Lake, a pristine but ominous caldera lake over two kilometers in diameter. The Millennium Eruption’s impact on regional populations remains the subject of archaeological and historical inquiry, with evidence suggesting widespread agricultural disruption and social upheaval in Korea, China, and Japan.
Despite its apparent dormancy, Mount Paektu is anything, but extinct. The volcano remains active, with geophysical studies indicating the presence of a sizable magma reservoir beneath its surface. Since its last recorded eruption in 1903, Mount Paektu has experienced episodic unrest. Between 2002 and 2005, significant seismic activity was detected in the region, accompanied by signs of crustal deformation and anomalous gas emissions. These indicators suggest that magma movement beneath the volcano is ongoing, increasing the likelihood of future eruptions. However, since that period, there have been no significant signs indicating an imminent eruption. As of early 2025, there are no reports of current eruptions or lava flows, and monitoring data has not shown any drastic changes in volcanic activity. Nonetheless, the volcano’s unpredictable nature means that continued vigilance is essential.
One of the primary concerns for volcanologists is the inflation of the underlying magma chamber. Ground deformation data, obtained through satellite radar and GPS measurements, suggest that pressure is gradually accumulating within the system. Additionally, increased concentrations of sulfur dioxide and carbon dioxide have been detected in the region, indicative of magma degassing at depth. Periodic low-magnitude earthquakes beneath the volcano further suggest that the subsurface magmatic system remains dynamic. Such activity is reminiscent of the precursory signals observed at other caldera-forming volcanoes, raising the possibility of a future eruption, though the timeline remains uncertain.
The prospect of a major eruption from Mount Paektu carries profound implications, both geologically and geopolitically. Given the volcano’s location along the North Korea-China border, coordinated scientific research and disaster preparedness efforts are challenging. North Korea’s political isolation severely restricts the ability of international researchers to conduct comprehensive studies, though limited collaborations have occurred, notably with the United Kingdom’s Cambridge University in the early 2010s. Despite these efforts, much remains unknown about the full extent of the magma system and the probability of a large-scale eruption.
A future eruption, particularly one on the scale of the Millennium Eruption, would have dire consequences for the region. Volcanic ashfall could devastate agriculture in northeastern China and the Korean Peninsula, leading to food shortages. Lahars and pyroclastic flows would pose immediate threats to settlements and infrastructure in the surrounding area. Air travel across East Asia would be severely disrupted, particularly if an eruption injected significant quantities of ash into the stratosphere. Furthermore, a high-volume ejection of sulfur dioxide could lead to temporary global cooling, disrupting weather patterns and monsoonal systems that are critical to agriculture in Asia.
Despite these risks, active monitoring efforts remain limited. While China operates seismic and gas monitoring stations on its side of the border, North Korea’s capabilities are largely unknown. Given the potential for widespread devastation, increased international cooperation in volcanic research and early warning systems is crucial. Mount Paektu is a sleeping giant, and while it may remain quiescent for decades or even centuries, history has shown that its eruptions can be both sudden and catastrophic. The scientific community must remain vigilant, ensuring that when the mountain awakens once more, humanity is as prepared as possible.
While I am extremely fortunate to live on a small hobby farm, I started learning about growing my own food as a pre-teen living in an apartment with a concrete yard using containers. My grandparents lived on a half acre with a greenhouse and cold frames, and this expanded my learning opportunities until I could get my own space. Wherever I have settled in the world, I have grow some level of my food, whether it’s been window sill herb gardens, raised beds on a small city lot, or a few acres of orchards, perennial fruit and veg, with rows of annual harvests.
There was a time when backyard gardening was seen as a hobby, something for retirees with time on their hands, or for children learning about where their food comes from, but in recent years, urban agriculture has become much more than a pastime. As food prices continue to rise and supply chains face disruptions, more people are turning whatever outdoor space they have – balconies, patios, backyards, and even front lawns – into productive gardens. The shift isn’t just about saving money; it’s about taking control of food security in an increasingly uncertain world.
The past few years have revealed vulnerabilities in the global food system. The pandemic exposed just how fragile supply chains can be, with empty grocery store shelves becoming a common sight. At the same time, extreme weather events linked to climate change have devastated farmland, reducing crop yields and further driving up prices. For many families, fresh, nutritious food has become harder to afford. The solution, in part, lies closer to home. Urban agriculture, even on a small scale, can help reduce dependence on imported produce while ensuring access to healthy food.
One of the biggest misconceptions about growing food is that it requires a large plot of land. In reality, a surprising amount can be harvested from small spaces. Balconies and patios can support potted herbs, tomatoes, and peppers. Small backyards can accommodate raised beds, which improve soil quality and provide better growing conditions. In denser urban areas, community gardens have emerged as a way for neighbors to grow food together, share resources, and build a sense of connection. Some residents are even experimenting with hydroponic systems, allowing them to grow fresh greens indoors year-round.
Beyond the personal benefits, urban agriculture plays a vital role in strengthening communities. When people grow food together, they build relationships and foster a shared sense of responsibility for local food production. Many community gardens serve as educational spaces where people learn about sustainability, organic farming techniques, and seasonal eating. Some initiatives even donate surplus produce to local food banks, ensuring that those in need have access to fresh, healthy food.
The environmental benefits are equally compelling. Green spaces in urban areas help reduce heat, mitigate stormwater runoff, and provide much-needed habitats for pollinators like bees and butterflies. Growing food locally also reduces the environmental impact of transportation, cutting down on emissions associated with long-distance shipping.
While urban agriculture isn’t a replacement for large-scale farming, it is an essential piece of the puzzle when it comes to food resilience. As more people recognize the value of growing their own food – whether for economic reasons, environmental concerns, or simply the satisfaction of harvesting something fresh from their own backyard – cities are beginning to adapt. Local governments are easing zoning restrictions, supporting community garden initiatives, and encouraging green infrastructure.
The future of food may be more localized than ever before. Urban agriculture is proving that solutions don’t have to come from massive farms or distant suppliers. Sometimes, they start with a single tomato plant growing just outside the door.
Single-crystal batteries represent a significant advancement in lithium-ion technology, particularly for electric vehicles (EVs). Unlike traditional polycrystalline cathodes, which are composed of multiple crystalline particles, single-crystal cathodes consist of a uniform crystalline structure. This design enhances durability and performance, potentially transforming the lifecycle of EV batteries.
Traditional polycrystalline cathodes are prone to cracking and degradation over time, leading to reduced battery capacity and lifespan. In contrast, single-crystal cathodes exhibit greater resistance to such mechanical stresses. Research indicates that single-crystal lithium-ion batteries can retain 80% of their capacity after 20,000 charge-discharge cycles, compared to approximately 2,400 cycles for conventional cells.

The uniform structure of single-crystal cathodes contributes to more efficient ion flow, enhancing battery performance. Additionally, these cathodes are more resistant to thermal degradation, improving the safety profile of the batteries. Studies have shown that single-crystal cathode materials provide remarkable performance and safety characteristics.
The adoption of single-crystal battery technology could significantly extend the operational lifespan of EVs. Longer-lasting batteries reduce the frequency of replacements, lowering maintenance costs and enhancing the overall value proposition of electric vehicles. Furthermore, increased battery durability can alleviate concerns related to battery degradation, a common barrier to EV adoption. Ongoing research focuses on optimizing the synthesis of single-crystal cathode materials to enhance their durability and efficiency. For instance, researchers have developed methods to synthesize durable single-crystal cathode materials, potentially extending battery life and efficiency.
Canada has been instrumental in advancing single-crystal battery technology, with significant contributions from its academic institutions and research facilities. Researchers at Dalhousie University in Halifax have conducted extensive studies on single-crystal lithium-ion batteries. Utilizing the Canadian Light Source (CLS) at the University of Saskatchewan—a national synchrotron light source facility—they analyzed a single-crystal electrode battery that underwent continuous charging and discharging for over six years. Their findings revealed that this battery endured more than 20,000 cycles before reaching 80% capacity, equating to an impressive lifespan of approximately eight million kilometers in driving terms. This research underscores Canada’s pivotal role in developing durable and efficient battery technologies that could significantly enhance the lifecycle of electric vehicles.
Single-crystal batteries offer promising improvements in durability, performance, and safety for electric vehicles. Their widespread adoption could lead to longer-lasting EVs, reduced maintenance costs, and increased consumer confidence in electric mobility.
For centuries, the way we represent the world on maps has shaped our understanding of geography, politics, and culture. Traditional projections, like the widely used Mercator, have long been criticized for distorting the relative sizes of continents, reinforcing a Eurocentric worldview. But over time, innovative cartographers have sought to challenge these distortions with alternative projections that offer a more balanced and accurate view of our planet. Two such approaches—the Cahill–Keyes projection and the AuthaGraph map—stand out for their unique methods of minimizing distortion and improving spatial representation.
The Cahill–Keyes map, an evolution of Bernard Cahill’s 1909 “Butterfly Map,” was refined by Gene Keyes in 1975 to create a more symmetrical, contiguous world map. Unlike the Mercator projection, which greatly exaggerates landmasses near the poles, the Cahill–Keyes map unfolds the Earth into an octahedral shape, forming an “M” configuration that keeps continents connected while reducing distortion. By presenting landmasses with a higher degree of spatial accuracy, this projection fosters a more holistic view of global geography. It has been praised for its educational value, challenging the parochial perspectives often reinforced by traditional mapping systems.
The AuthaGraph map, developed in 1999 by Japanese architect Hajime Narukawa, takes a different approach. Using a complex method of dividing the globe into 96 triangles and transforming it into a near-rectangular form, this projection maintains proportional relationships between continents and oceans better than most existing maps. The AuthaGraph gained significant recognition after winning Japan’s Good Design Grand Award in 2016, and has since been used in scientific and educational contexts to provide a more accurate representation of Earth’s geography. Unlike the Cahill–Keyes projection, which prioritizes contiguity, the AuthaGraph sacrifices some familiar visual continuity to achieve an exceptional balance of size and shape accuracy.
Both of these projections challenge outdated methods that have long influenced global perceptions. The Mercator map, despite its usefulness for navigation, has historically exaggerated the importance of northern regions while diminishing the size of Africa, South America, and other equatorial regions. These distortions have subtly reinforced geopolitical biases, making alternative projections like Cahill–Keyes and AuthaGraph essential tools for rethinking our worldview. While no single map can perfectly translate a three-dimensional Earth onto a two-dimensional surface, these newer projections push the boundaries of cartography, offering fresh perspectives that align more closely with reality.
Beyond their technical advantages, these maps serve a broader purpose in education and global awareness. The Cahill–Keyes map emphasizes planetary unity by maintaining continent contiguity, making it particularly useful for fostering a connected understanding of world geography. The AuthaGraph, with its emphasis on accurate proportions, is invaluable for scientific applications, such as climate modeling and oceanic studies. Both contribute to a growing movement that seeks to correct historical inaccuracies and promote a more equitable, data-driven representation of our planet.
In the end, cartography is as much about perspective as it is about accuracy. The Cahill–Keyes and AuthaGraph maps remind us that the way we visualize the world shapes the way we think about it. By embracing innovative projections, we take a step toward seeing Earth not just as a collection of distorted borders, but as a dynamic, interconnected whole.
This is the first in a series of articles on freshwater—our most essential and increasingly fragile resource. Potable water is the foundation of any thriving community, yet it faces mounting threats from rising demand, population growth, mismanagement, and climate change. Water scarcity is no longer a distant concern; it is a present reality affecting billions worldwide, including regions of the United States. The urgent challenge is to adopt sustainable practices and modern infrastructure to ensure long-term water security.
The widening gap between supply and demand is at the heart of the global water crisis. Expanding urban populations and agriculture—by far the largest consumer of freshwater—are pushing resources to their limits. This strain is worsened by inefficiencies such as outdated irrigation techniques and aging, leaky infrastructure that wastes millions of gallons daily. Industrial and domestic waste further degrade freshwater sources, as pollutants like heavy metals, pesticides, hydrocarbons, and microplastics seep into rivers and lakes, transforming them from lifelines into health hazards.
Groundwater depletion is an equally pressing concern. Aquifers, the vast underground reserves that sustain millions, are being extracted at unsustainable rates, often faster than they can naturally recharge. In many regions, these reserves are the sole source of drinking water, making their preservation critical. Overpumping leads to land subsidence, ecosystem damage, and in coastal areas, saltwater intrusion, rendering once-pure water undrinkable. Without intervention, many communities risk losing their most reliable water source.
Climate change amplifies these threats. Shifting precipitation patterns disrupt the natural replenishment of freshwater supplies, while glacier retreat and prolonged droughts further reduce available water. The consequences are most severe in arid and semi-arid regions, where communities already struggle with limited access to clean water. Extreme weather events, such as hurricanes and floods, can also overwhelm infrastructure, contaminating water supplies with pollutants and pathogens.
Addressing these challenges requires a fundamental shift in water management. Advanced technologies such as drip irrigation, wastewater recycling, and desalination offer viable solutions to improve efficiency and expand supply. Equally important is public engagement—education and incentives can promote conservation at the household and community levels. Governments, industries, and local communities must work together to develop policies that prioritize equitable water distribution, pollution control, and long-term sustainability.
Freshwater is our most valuable natural resource, yet it is treated as an afterthought. Without immediate action, shortages will become more frequent and severe, threatening food production, public health, and economic stability. In the coming articles, we will explore the key dimensions of this crisis in greater depth, examining solutions that can secure a sustainable water future.
