Some of these personal devices take the form of little square boxes you carry around. Maybe others you can wear, like a pair of gloves, or sneakers, or glasses.
If you were taken on a quick visit to this awesome place, can you imagine looking at any of these devices and thinking, "Omg, that alien looks ridiculous. Its telebox is 7 inches instead of 4 or 10." Or, "Omg, that alien's glasses have a box thingy on the side. It looks aweful." No, you would not do this. Not in a million years. The thought would not even cross your mind. You would be so impressed and awed by the simple fact that the technology exists that it really wouldn't matter what form it took. And you would be dumbfounded by anyone letting those details get in the way of shaping their opinions about these amazing technologies.
If you were on this vacation, and you overheard one alien make fun of another because of the way one of his devices looks, you probably wouldn't even understand what was going on. Why do they care about those specifics? The technology is just so obviously cool that picking on the details seems... below their intelligence.
But we, here, on Earth, do this. We have the future in our fingertips, and now on our heads, and people actually take the time to criticize it for the way it looks. "Glasses look stupid." "Phablets are disgusting." Etc. As if not looking ridiculous is of higher value than anything new technologies can provide.
I think that way of thinking is a little sad. If you don't want to embrace new technology because you think it'll make you look silly, then don't. Why on Earth would you take the time to criticize those who don't give a fuck, who are willing to embrace new technologies because of what they do, and not how they look?
As a 26 year old, I can't wait to get my hands on a pair.
