hmm, I think I know what I want to learn and experiment with, besides FPGAs...

Deep Molecular Programming:
A Natural Implementation of Binary-Weight ReLU Neural Networks
> Embedding computation in molecular contexts incompatible with traditional electronics is expected to have wide ranging impact in synthetic biology, medicine, nanofabrication and other fields. A key remaining challenge lies in developing programming paradigms for molecular computation that are well-aligned with the underlying chemical hardware and do not attempt to shoehorn ill-fitting electronics paradigms.
