Yeah but ChatGPT is using $700k per day in compute (or was in April). Someone's going to make an analog machine that uses mirrors and light interference or some

  Yes, this is an active area of research. Neural networks are a very good application for analog computing (imo). You have a ton of floating point operations that all need to happen more or less simultaneously. And what are floating point numbers if not digital approximations of analog values? :) This can be implemented as a network of transistors on a chip, but driven in the linear region instead of trying to switch them on as hard as possible as fast as possible. Which is, I believe, what researchers are trying to do. There are also some interesting ideas about photonic computing, but I'm not sure if that's going anywhere. A few months back, someone on YouTube attempted to design a mechanical neural network as a single 3D printed mechanism. It ended up not working, but the concept was pretty solid.
