> that's actually one of the main problems with analog systems, it's much easier to create a use-case specific instead of a general purpose one. the forward-forward paper looked promising and that was two years ago, which is a lot of time. with a variation of that you could train analog chips where each virtual neuron is made with a couple of transistors and a capacitor, or some other memory device, using the analog curve of the transistor directly, non-linearity and all. i'm surprised nothing like that has come out yet.
