This is an uninformed take. Currently, ai is just computers. Computers can only make things on the computer. Ai is not yet robots. Robots is much harder to do than computers, and they are made to do one thing. Stuff like folding clothes is not one thing, but a whole bunch of individual ones.
You're taking it too literally. It's metaphorical. No one thinks China has AI robots doing laundry any more than they think AI is physical robots in the US using a paintbrush and physical easel to do art. Well... I'm sure some burgerbrains exist who think that, but you know what I mean. (Edit: turns out I don't know how to spell easel).
Why make the distinction between robots and PCs/servers? There doesn't seem to be any fundamental difference between them that would make implementing ANN impossible.
Not sure how this makes using ANN in robots impossible. Surely you don't think that electronics can't be used in robots, do you?
Hell, it's been a while since I programmed LEGO robots, but I'm pretty sure you can write an ANN there using official tools. This is all just a matter of having some programmable component in a robot and enough memory.
