There is a lot of computational chemistry and biology done in the early stages of research - there are now multiple orders of magnitude of computation power available that is doing nothing but feeding forward on billions of random numbers.

On the other hand, AI means actual experiments done in the physical world but coordinated by an entity that never sleeps and never gets depressed and can multiply itself manifold and always comes up with new ideas.

That fanatical tireless entity will need access to human tissue.

Please don't give them ideas

I assure you they already have these ideas

And hands.
