The day they are available as a platform to teach them skills and make them do things like we need it!
they are listed for $30k on Unitree's site, I'd get one if I could justify it, will wait a generation or two longer
For now it's just a gadget with no real world function, just an early adopter toy. And a very expensive one by my abilities. But it feels like humanoid robots are inching along on the horizon, in the near future they'd likely be able to fill some niches if not replace a lot of labor. I'd wait too, unless you want to pay lot of money to be a beta tester.
I got excited for this space when I saw the ALOHA project for a DIY robart arm cart with low training sample on new tasks. It came in around $35k a few years back
