i don't think that, lovely though she is, i wan't cara to pop up in my glasses (which, because of bad eyesight, i wear all the time) and no, i do not think we have the technology, particularly batteries. i will admit that if i could ask my glasses "where is the nearest atm?" and it then popped up an arrow pointing at it, i might pay for that. but that means stuffing a lot of hardware into the frames - about the equivalent of a high-end smartphone.
