AI Has a Cost Now

This episode looks at an idea from something Satya Nadella said — that AI has introduced marginal cost to software for the first time, meaning every query, every prompt, generates a real computational expense in a way that copying a piece of software never did.It touches on why that's a break from how the digital world has always worked: music, video, software could all be reproduced endlessly at near-zero cost. AI doesn't follow that rule, and that changes how you have to think about using it.There's also a parallel drawn to fitting eyeglasses — how arriving at the right lenses requires combining prescription, lifestyle, frame shape, and facial structure, not just picking the most advanced option available. Designing with AI, the episode suggests, follows the same kind of logic.A bike-ride analogy comes up too: carrying two liters of water on a long course isn't about minimizing weight or maximizing supply — it's about finding the amount that gets you to the finish line fastest, for that specific route.A quiet reflection on the idea that AI is beginning to feel less like free-to-use software and more like electricity or labor — something that rewards careful thought about what you use, how much, and why.
