What fields do you expect these hyper-parallel experiments to take place in? Advanced robotics aren't cheap, so even if your AI has perfect simulations (which we're nowhere close to) it still needs to replicate experiments in the real world, which means relying on grad students who still need to eat and sleep.
Biochemistry is one plausible example. Deep Mind made hug strides in protein folding satisfying the simulation part, and in vitro experiments can be automated to a significant degree. Automation is never about eliminating all human labour, but how much of it you can eliminate.
