I think Optalysys looks interesting! For the curious, Optalysys has built a general purpose optics-based correlation/pattern matching machine. From some of their predecessor-company marketing material: The correlator performs pattern matching on large data sets such as high-resolution images, providing a measure of similarity and relative position between objects within the input scene. This allows large images [and general data converted to images] to be analysed far faster than electronic equivalents. Going back to the topic of NN-based computing, I found this talk to be intriguing: https://www.youtube.com/watch?v=dkIuIIp6bl0 https://www.youtube.com/watch?v=dkIuIIp6bl0. The main argument is that because Moore's law may no longer be in effect, it will become increasingly important to explore alternate computing solutions. (Google's TPU could be supporting evidence for this argument.) The speaker also co-authored a paper which I liked "General-Purpose Code Acceleration with Limited-Precision Analog Computation".

This video was very cool. Are there any IC's that can perform analog computing for neural networks on the market now? I'm picturing something like an FPGA but with a bunch of op amps that you can connect into summers or amplifiers. If not, how would one practically implement an analog computer for neural network programming (without several tables full of op-amps?)

  Glad you liked the video! You can implement an analog neural network yourself using a Field Programmable Analog Array. (I've never done it, but you'll see academics online writing papers about it.) Another thing that is sort of related is Lyric Semiconductor; they built these cool application-specific probabilistic processors; they were purchased by Analog Devices a while back.
