Smart glasses as display-only don’t get enough love as a concept. You can already buy these, although birdbath displays have the weakness of being visible from outside as well.

The other stuff is still pretty speculative, I don’t see any reason the technology is all that much closer when it comes to reading minds or reliably interpreting complex spoken instructions. Sure, smart phones are all the same, but they’ve been that way stably for many years now. Ditto for cars and mops and any number of other things.
