Don't point that thing at me
With this whole "attaching of outward-facing cameras to eyewear" thing going on, I think I should bring up a Tweet which seems to have been forgotten lately:
My new standard of cool: when I'm hanging out with you, I never see your phone ever ever ever.
When this came out, a whole bunch of people I know seemed to be on board with the overall sentiment expressed here in surprisingly few characters.
Now we're talking about people who go around aiming a camera at you the whole time, and who are probably fiddling with a display only they can see. They're still not paying attention to you, and now there's the situation of having your picture taken, too.
How quickly we forget.
