The only difference is that now we know that walking along the pavement avoid those rude and stupid enough to think they can walk and text at the same time is as difficult as it is annoying. In the 1990′s, we could only guess that would be the case. When you can’t even see who’s texting because they’re not carrying a phone, dealing with these people will be an order of magnitude worse than it is already.

People cannot pay attention to the device and drive at the same time.

Now, people using these glasses will have even less incentive to pay attention to what is happening around them.

Yes, you are being childish.

I agree John. I also found the linked article, which points out the challenges to usable AR glasses, well thought out and interesting.

But the genie is clearly out of the bottle. There is a buzz around this and people are clearly very excited.

Which makes me wonder – why did Google release the video now? Perhaps in part it is to gauge the interest in the project and figure out how much money and resources to devote to the program? You can measure the buzz now – just look at your Tag Cloud.

No that we’ve seen it, this isn’t going to take 20 years.
