(1) Simplistic because it isn't binary, solved vs. not solved. There's still improvement to do in the solution. And we won't really know if it's “solved” until we start trying to use these structures for practical purposes. Don't mean to detract from the accomplishment overall though, it seems tremendous.
(2) There is a certain amount of computing needed for each new protein---quite significant, I think, but not prohibitively expensive. And I'm sure this can be improved over time
I have a couple of questions, which might be related
(1) Why did you call it out as "simplistic"?
(2) Will the DeepMind team have to throw the same amount of computer power at each structure they seek to solve?
