Modern robots are nowhere near being bottlenecked by hardware. They are all bottlenecked by AI. Today's hardware with perfect AI would absolutely demolish tasks like "clean a house". Today's AI with perfect hardware would still fumble.

We know that because we can't even train an AI policy that would reliably solve tasks in a sim with perfect sensors and perfect execution.
