Certainty in the reverse direction (Google Glass will change the world!) is just as silly, though maybe a little less curmudgeony.
Reality is that our first impression of a new technology is pretty much a coolness measure. Some things look cool and everyone who sees it wants it but are not ultimately useful or impactful (eg segway). Its really hard to tell how important some new technology is.
"Puke. I find Glass to be ugly, impractical and completely ridiculous."
And I find Glass to be elegant, useful, and futuristic. So where does that leave us?
And then this:
"they simply don't know what it means to make products that make people happy."
Are you serious?
