In whose deluded mind would censorship NOT be "exactly the right word for it"??
The problem is, nobody wants to wear glasses, even people who need them for vision correction. That's why contacts were invented, and laser vision correction. So why, oh why, would we ditch glasses, only to wear different glasses.
Because normal glasses imply that your eyes are faulty and people don't like announcing thier flaws in such an obvious way if they could help it. Because normal glasses imply you do a little bit too much book readin', so you obviously need to be picked on. Conversely, Google Glass doesn't try to correct a physical impairment you have, so it isn't really a fair comparison.
