Moravec's paradox says that tasks we find hard, like chess, can be easy for machines, while tasks we find trivial, like folding a shirt, are brutally hard.

Cloth changes shape with every touch, so the robot must see and plan constantly. Progress is real, but the folding machine in every home is still a few laundry days away.

Why it is in the vault: it is the kind of find worth coming back to. Add sources, corrections and related links in the discussion thread.
