The common analogy of AI to electricity is dangerously rosy. AI is more like fire: a transformative tool that, if mismanaged or weaponized, can spread uncontrollably with devastating consequences. This mental model better prepares us for AI's inherent risks and accelerating power.

Post-WWII, economists pursued mathematical rigor by modeling human behavior as perfectly rational (i.e., 'maximizing'). This was a convenient simplification for building models, not an accurate depiction of how people actually make decisions, which are often messy and imperfect.

Traditional economics often repels people with complex math. Economist Kate Raworth intentionally used the simple, non-threatening metaphor of a "donut" for her alternative economic model. This disarmed common fears around the subject and encouraged broader, more accessible engagement.

The way we grow food is a primary driver of climate change, independent of the energy sector. Even if we completely decarbonize energy, our agricultural practices, particularly land use and deforestation, are sufficient to push the planet past critical warming thresholds. This makes fixing the food system an urgent, non-negotiable climate priority.

Setting rigid global warming limits (e.g., 2°C) creates a finite carbon budget. Since most future emissions will come from developing countries, these caps effectively tell poorer nations they must cut projected emissions by up to 90%, forcing them to choose between development and global climate goals.

The dominant economic model pursues endless growth, often at a human or planetary cost. Donut Economics reframes the goal entirely: create economies that allow humanity to thrive by meeting essential needs while respecting planetary boundaries, irrespective of continuous GDP growth.

Rapidly scaling companies can have fantastic unit economics but face constant insolvency risk. The cash required for advance hiring and inventory means you're perpetually on the edge of collapse, even while growing revenue by triple digits. You are going out of business every day.

Afeyan proposes that AI's emergence forces us to broaden our definition of intelligence beyond humans. By viewing nature—from cells to ecosystems—as intelligent systems capable of adaptation and anticipation, we can move beyond reductionist biology to unlock profound new understandings of disease.

Modern capitalism profitably hacks primitive human drives (e.g., junk food, social media), redirecting them away from natural behaviors like reproduction. This cultural trajectory could be an evolutionary dead-end, where the system selects against its own continuation by fostering sterility, paving the way for its replacement by a different culture.
