Thoughts on AI, technology, thinking, and building products.
Product Still Matters
AI made software cheap to build. It did not make good products less important. It made product judgment harder.
The Review Paradox
AI's biggest productivity gain is the work you couldn't do before. Most measurements miss it completely.
The Harness Is the Product
Why the next decade of AI gets built around the model, not inside it.
The Turbines Are Sold Out. The Sun Isn't.
Gas turbines: 5-year wait list. Solar in orbit: 5x more energy per panel, no batteries, no permits. The whole pitch reduces to one number: dollars per kilogram to launch.
Why kids will turn to AI first
Why AI has an edge with kids as both teacher and therapist
What's left for us
AI is getting good at most things. Four areas where I think humans still have an edge, at least for a while.
All brain, no hands
The brain-and-hands model shows what makes AI powerful. The performance triangle shows which setup fits the task.
Do the reps
The MIT measured what happens when AI does the thinking for you. Harvard found a better way to use the same kind of tool.
The AI energy panic is missing half the math
What happens when you compare AI energy consumption to the real cost of having a human do the same job?
On AI temperament
Why the best AI users don't pick one model. They build a team.
A tribute to trigonometry (and my dad)
My dad went from architect to trigonometry teacher. It took me 20 years to understand why that wasn't a step down.
