Logistics tend to be improvable with more inteligence though, no?
There is precedence for superhuman inteligence if you look at the best historical polymaths, and that's just what one can do with 20 W of energy. We're probably nowhere close to the universal inteligence cap in terms of physical limitations, if there even is such a thing.
Sure but then you need to manually do the back and forward whenever you hit a new bottleneck. At some point the intelligence might need to figure out better power sources and deliver to feed bigger clusters of compute. Those clusters need to physically be deployed somewhere in the real world also, etc.
Would you ever know if a robotic intelligence was burrowed underground quietly powering itself from the heat gradients and slowly turning rock and sand into more machine?
