Tim Cook also pooh-poohed headsup displays as a barrier between people, instead of connecting them. But, since earplugs and people checking their phones already disconnect people, this seems like diversionary bs to me. Apple is surely working on this, as they work on many things.

Small displays are the problem, bigger phones are popular despite their awkwardness. Headsup displays solve both: large display, out of the way.

Not sure about input; gesturing to yourself is going to look even crazier than talking to yourself.

In the early seventies I used to carry my Philips portable cassette player and headphones everywhere, people thought I was crazy until Akio Morita had the same idea and got Sony to create the Walkman. Now people wear headphones in the street and hardly anyone thinks about it at all.

My point is that what you think is crazy now might well be normal in ten years time, or perhaps even tomorrow.

That sounds painful.

(The word you are looking for is pooh-poohed.)

Wonder if it's technically possible...
