World models (AI that understands how physical things happen and the physical environment) will show up in 3-4 years, starting to show up now with super early research previews.

This matters because robots like Optimus are waiting for them.

That said, a hand is not necessarily the best tool for task execution and confirmation. I agree that humanoid++ is probably a pretty good way to move around, but disagree on hands.

I think we will se robots with more like 4 hands/arms.
