About
Everything has structure. Finding it lets you see the same thing through different lenses — a system, a product, a market, a decision — and I try not to respect the borders between them. Lately that mostly means AI, building products, and how to think well about both.
I get distracted by how things work. I'm wrong a lot, and mostly just try to be wrong faster than last time.
