The problem is sensors.
There are simply no technologies today that can replicate the density, precision, and versatility of human touch sensors. Until then, there is simply no way to create generally capable robots that can operate at the level of a human.
And unlike LLMs, advancement is held back by physical limitations like materials science, so progress has been and will continue to be much slower.
If you look you will see a really broad range of tasks accomplished already, including thing like manipulating screws, picking up pills, inserting wire harnesses, folding clothes, putting away dishes. And there are several companies with built in or component advanced touch sensors like Figure or leading edge touch sensor companies like SynTouch and GelSight.
Sure, build an orange peeling machine and it'll do great. But that's not what we're talking about here.
As for those demos videos we often see, those are very highly choreographed demonstrations. Show me a real life humanoid robot operating free form on a factor floor and doing those things and I'll be impressed.
And to be clear, this is not meant to understate what's been accomplished. I'm just saying the path for advancement is a lot harder and based in physical rather than computational limitations, which are much harder to overcome and go much slower. We simply cannot look at the growth curve of LLMs and expect robotics to advance at the same rate.
keep paying attention, you will see how wrong you are about it being physical limitations as the physical AI continues to rapidly improve.
