Lol what. We can't even define "true intelligence" and you're telling me the "mechanics" are already solved? What do you even mean by that statement?
The control systems/software is different problem, and then there is power (current gen lasts a few hours at most, depending on application this may be a problem or it may not be)
I agree. Other than the control system, everything else is already there, or at least understood. But I think we are much farther away from "true intelligence" than AI boosters claim. We don't even know the path to it. We have guesses, but no hard evidence that those guesses will actually pan out.
