This is kind of a cool computer, but it's not a serious approach for most problems, and doesn't have much to do with the original article. Analog computers have very limited precision due to SNR, and this kills their usefulness for almost everything aside from niche simulations and machine learning.

It's like how people have been saying lisp is the future of coding.
I feel most engineers (including myself!) become enamored by beautiful ideas enough that they'll want to try applying it to places it doesn't really work.
Doesn't mean I have to stop dreaming of a plan9 flavored 100% Lisp OS though!
