I used to work for Apptronik, and for several other humanoid projects. These robots are not going to be doing tasks that are at the edge of human dexterity any time soon. They can barely drop objects into boxes.

Edit:

I saw a video a few days ago from Figure where it was putting dishes onto a dish rack at relatively high speed and that was genuinely impressive, possibly the best object manipulation I've seen. But that's still closer to dropping objects in boxes than to the welding and wiring work that I've done.

Fixed machinery already does most of the welding in automotive manufacturing. Changing that to a movable base doesn’t seem like an impossible problem especially if you can use a fixed point on the object and then use relative coordinates like a CNC machine. I could easily see a robot pulling out stamped metal parts, making a couple of welds and then stacking them up.
