Well I mean even with the Apple headset right now you don't even need thumb commands you just look at what you want via eye tracking and it can register what it is you want. There are only simple pinch movements for selecting things but not for navigating.
Unless your argument is this tech will never get down to glasses level, but I think that's foolish. It will get there, just a matter of time.
Did you really think smartphones would forever and ever be the only end product computing platform ... kids in 20, 30 years will laugh at that, same as kids today laugh at a rotary phone and even a CD player.
But a CD player or rotary phone doesn’t hurt your eyes.
Those devices were replaced by things that did their job better. Cordless phones with touch tone buttons were better than rotaries.
They were in turn replaced by cellular phones, and ultimately rendered obsolete by smartphones.
CDs replaced cassettes, and were then replaced by mp3 players, which were replaced by iPods, which were replaced by streaming.
You can clearly see how each technological advance improves upon the previous one.
I’m certainly willing to be wrong, but I do not see what this offers that’s superior to the smartphone in an everyday use case.
Smartphones are with us and turned on 24/7, and stay that way until they’re replaced.
You can’t do that with glasses.
