Sounds like really neat work. It reminds me of an idea I've toyed with just a little: you know how chemical reaction networks can compute? E.g. https://johncarl

Sounds like really neat work. It reminds me of an idea I've toyed with just a little: you know how chemical reaction networks can compute? E.g. https://johncarlosbaez.wordpress.com/2014/03/23/programming-with-chemical-reaction-networks/ https://johncarlosbaez.wordpress.com/2014/03/23/programming-... Last I heard, they'd used DNA strand displacement in vitro for simple neural network stuff. So I wondered how practical it'd be to encode a Bayes net as a reaction network, with the Gibbs sampling done directly by thermodynamics. This wouldn't compete with the sort of thing we do in silicon; maybe it'd work out for tiny diagnostic systems in synthetic bio? With less overhead than the neural nets. (Well, that took more space than I wanted. I downloaded one of your circuits papers for a gander.)
