Formal methods stopped being academic
Proof used to mean a paper. seL4 shipped a verified kernel, and verification tooling for ordinary languages is now something a working engineer can point at a bounded problem.
The protein problem became a data problem
A neural network won CASP13 outright, and a sequencer that runs off a laptop's USB port costs less than a server. Biology is becoming a field where the expensive instrument is a model and the cheap instrument fits in a coat pocket, which changes who is able to do the work and who ends up holding the data.
