Ha! I have spent the last 2 years on this idea as a pet research project and have recently found a way of learning the wiring in a scalable fashion (arbitrary number of input bits, arbitray number of output bits). Would love to chat with someone also obsessed with this idea.
I also I'm very interested. I had played around a lot with Differentiable Logic Networks a couple of months ago and how to make the learned wiring scale to bigger number of gates. I had a couple of ideas that seemed to worked in a smaller scale, but that had trouble converging with deeper networks.
Also very interested. Do you have any code on github?
