Yes, I definitely agree with your sentiment there... but I guess I should point out, that there were also many things in the past that were thought to be a good/bad idea at the time... and proved with modern knowledge to be bad ideas!

Wearables would definitely be a great interim step! I had really been caught by the idea of the Google Glasses and the concept of it... however, I had much less interest in the watches and that sort of thing.. Something about watches seemed less integrated than a HUDS interface.
