We're at a time where almost literally every single book every written is with me in my pocket everywhere that I go, as well as every piece of music ever recorded, and every film ever made.
I have the world's largest library, bigger than anything that the Greeks or Egyptians could have even dreamed, and I carry it with me, every day, in my pocket; most of the people I know do too! We're all constant patrons to humanity's most complete and largest collection of art and information.
And now this library is being made even more available to me. I can immediately call up the sum of human history just by glancing in my peripheral...
...and this scares you? You don't like it?
Is this fear?
Certainly there will be assholes. One of the saddest things I saw last year was people at burning man constantly hiding behind a gopro or other camera, and I called them out on it constantly "be here with me! Don't hide behind that lens!" etc.
But these people have existed forever. There has always been cameras.
And for distractions there has almost always been books.
The glass isn't "new" in that sense, it's just better.
That has obvious pluses, but it's foolish to ignore the minuses on the other side.
It will always be there, always demanding a fraction of your attention.
You'll get used to it, certainly. But that won't mean that it's not taking part of your attention. It will just mean you got used to it taking part of your attention.
The question is how much attention we have to spare.
At present, too many people equate "having literature on your cellphone" with "understanding that literature." For certain types of information (e.g. manuals, data tables) having a searchable format is almost as useful as already knowing the contents. Having a searchable copy of Hamlet, however, is not nearly the same thing as having read it. When the day comes that I can have a ethernet port in my head, and downloading a text file of Hamlet is virtually the same as having read it with my eyes, I will gladly sign up. But until then, looking around at all the people with various headsets, phones, and now Google glasses, I will chuckle to myself, because all I see are glassholes missing out on the world around them.
In the same way that these technologies have made data access easier, they've made being a rude asshole easier. There have never been more ways to not pay attention to the person talking to you, and to put a digital wall between you and the people you are supposed to be interacting with.
Information has existed forever. Tech makes it more accessible. Assholes have existed forever, but tech introduces brand new ways to be an asshole.
At best they'll have to fidget with the device less and might be marginally less distracted, but this is still just making the problem easier to cause. You're happy to have all the media in the world at your fingertips, and that's understandable; however, now everyone can have all that media right in front of them, between them and you, very easily.
Maybe I'm just very short-sighted (I do have an awful prescription, har har), but I see absolutely no way this could do anything except make the problem you describe worse.
Changes in technology have a fundamental impact on the way humans interacting with the world (for better or worse), an interesting book called The Shallows [1] highlights some of these points. Is the technology we're utilizing moving us in a direction that is long-term beneficial or harmful? People can access information more easily, but at the expense of what - lack of focus? Problems with deep thought and long-term planning?

As for your assumption re:engineers/programmers, I am just a full-time lover of tech news and a part-time cynic of where what I read will take us.
For those who have seen the film Children of Men, there's a scene in there of a young man in a nice apartment who is playing video games on a strange, futuristic headset which, if I remember correctly, somewhat resembled Glass. He looked like he had psychological problems.
We're getting closer and closer to Surrogates/Gamer/Sleep Dealer/etc, something I'm not excited about at all.
