Changing tastes: Can technology sustainably feed the world?

Canada has always run on water. In the 19th-century, thousands of communities developed around the textile, grist and saw mills that harnessed water power from rivers. Today, hydro generates about 60 percent of the country’s electricity. But as demand strains the grid more with each passing year, could the dams that once served those now-dormant mills provide a new source of power? That’s the vision of Andrew Murray and his startup, Aslan Renewables. During COVID lockdowns, Murray went on long walks with his father throughout rural P.E.I., where his father pointed out the untapped potential of the dams they passed. Murray seized on the idea and developed a compact, modular turbine system that used the elevation of these dams to generate reliable, clean energy. In this episode, Murray discusses our current energy crisis, why small-scale local power generation is so vital and how he’s transforming timeworn infrastructure into a technology of the future.

Recent advances in AI have fundamentally changed how we predict the weather, making forecasting cheaper, faster and better — we can now track even the most unusual weather event with almost pinpoint accuracy. Such accuracy has never been more urgent. With climate change making weather more extreme, unpredictable and dangerous, knowing how much rain a storm may bring, or how long a drought could last, can be a matter of life and death. In this episode, we explore this quiet revolution in forecasting, why this knowledge must also drive policy change and, in the face of growing water shortages, how AI is helping us tap an unexpected new source.

Episode summary: The head-spinning ascent of AI is a story of scientific innovation, but it’s also, fundamentally, a story about money. Between 2013 and 2024, AI netted about U.S.$1.6 trillion of global corporate and private investment; it’s estimated that by the end of this year that number will reach U.S.$2.5 trillion. How this massive investment is transforming — and will transform — the way we live and work is a matter of fierce debate and great uncertainty. One person at the centre of this technological and economic maelstrom is Pillar VC’s Leah Morris. She’s the executive director of Pillar’s Encode: AI for Science fellowship, which provides AI researchers the time, freedom and resources to build meaningful, game-changing solutions. In this bonus episode, she discusses how new technologies are exacerbating economic inequality, the enduring value of human judgment and how the AI investment landscape is too often, in her words, “bullshit in a bull ring.”

Thanks largely to advances in AI, robots are now capable of things never before possible: picking delicate vegetables, moving heavy goods deftly around a warehouse, making pizzas. But there are still limitations to even the most sophisticated and expensive machines. Replicating human dexterity, for example, remains a surprisingly fiendish challenge. While some experts talk about an imminent “ChatGPT moment” for robotics — one that has the potential to completely transform society — it’s not quite clear when this moment will arrive, or what it will mean when it does. In this episode, we explore how new robot technology is reshaping society, the economy and our understanding of what it means to be human.

The housing crisis is fundamentally a health problem. Decades of research show that people experiencing homelessness spend twice as long in the hospital, cost the healthcare system double and have a life expectancy half that of the average Canadian. In this special episode of Solve for X: Innovations to Change the World, recorded live at a MaRS Morning event, host Manjula Selvarajah sits down with primary care physician Dr. Andrew Boozary to discuss a radical shift in Canadian medicine: treating housing not just as a social service, but as a critical medical intervention. As founding executive director of UHN’s Gattuso Centre for Social Medicine, Boozary shares data-driven insights from his initiatives there: prescribing nutritious food boxes, the launch of Ontario’s first hospital-based homelessness and eviction program and, most famously, the establishment of Dunn House, a permanent supportive housing model that’s proven to be both effective and scalable. Together, Selvarajah and Boozary explore what it takes to dismantle bureaucratic sludge, cut through systematic fragmentation and build a healthcare system rooted in human dignity.
