NN's do not need to be analog machines. Some networks perform quite well on digital
machines. Of course if you're implementing a Net based on arithmetic propagation
as is used in backprop and many others an analog machine would be best.
I use ALNs and they're ideally suited for a digital enviroment.
What I am trying to iterate here is that just because your version of a NN would
run best on an analog machine it doesn't mean that all NNs should be analog.
