I don't know, man. I'm not in love with glass or anything, and I have no plans to buy a pair, and some of the criticisms are valid, individually at least, but collectively the anti-glass crowd reminds me of buggy makers laughing at the first cars as they sputtered and spurt down the road, frequently getting stuck or breaking down.
Yeah, it's kinda pointless right now. But meta reality is coming whether you like it or not, and this is just the first stab. ANY new technology is expensive at first. ANY new technology has minimal practical application at first.
So I would say, critics beware.
