# 付铖 · Fu Cheng

Shanghai. I build AI companies and write about where this is all going.

I bet — with real money and time — on a few things: the marginal cost of intelligence is going to zero, energy is the only currency that survives that, and the fat margins of SaaS get taken apart one pillar at a time. Everything below is me working that out in the open.
