You could achieve the same by wearing a GoPro on your head.
But a gopro on the head, or a phone held up to record, is much more conspicuous. These smart glasses are made for ppl to record their life 24/7. That automaticlaly means, other ppl's lives will be recorded by that person. Without their knowledge.
It is also bad with a gopro or a phone, ofc. But smart glasses make the prob even worse. That doesn't even get into the uses these will be put, creeping on women at beaches or w/e. If you go holding up a phone to creep somebody, there is social pressure to stop being an ass. You may even be asked to leave the venue. But when it is unobtrusive with smart glasses, the social pressure erodes b/c people don't even know.
I agree automatic upload is a prob. But even if it's local, the mere fact of walking around recording everything you see, means other ppl's worst moments are going to feature in tiktoks a LOT more often. And much more clickbait content made at the expense of ppl who don't even know they are being recorded, trying to make them look bad for the content. I agree, that happens already in other ways. But that doesn't mean we should want to see the prob get even worse.
