It’s plausible in a sci-fi sort of way, but where does the model come from? After a hundred years of focused study we’re kinda beginning to understand what’s going on inside a fruit fly, how are we going to provide the machine with “a perfect model of all interactions between biological/chemical processes”?

If you had that perfect model, you’ve basically solved an entire field of science. There wouldn’t be a lot more to learn by plugging it into a computer afterwards.
