Smart clothes are smart
Not smart as in hey what a snappy dresser. Smart as in more bulletproof, more fireproof, and capable of capturing sound waves and converting them to energy so you can charge your phone by plugging it into your shirt at a ball game. Also: boots that generate electricity from you walking around. This is the future, apparently, as described in a fun Popular Science slideshow on what we'll be wearing in the future.
I'm kind of dubious, though, because everyone knows that in the future we'll all wear silver jumpsuits.
