Why weren't you bitching about those 30 years ago?
How do you have any idea what I was or was not bitching about 30 years ago? What a strange argument.
Yes, spy cams have been around for decades. But they weren't mass marketed and sold in the millions, over 7 million Meta glasses just last year. And, 30 years ago, it was much more difficult to upload, share and access videos from said spycams. Today, a video shot in a random Walmart in southern California can be viewed nearly anywhere in the world in moments; and getting it taken down once it is broadcast globally is nearly impossible.
It's not like people are using these glasses to film their child's soccer game. People are wearing them, filming all the time, with the hope that some rando will do something stupid or weird or odd and they can then go viral and make $$. While as a member of said public, it means feeling like you are being filmed all the time everywhere by strangers for the purpose of the LOLs or to even have your image and likeness abused, manipulated, distorted in harmful ways. Even though most said filming in public places is technically "legal," I find it intrusive, offensive, rude, and boorish behavior that has been enabled and made simple and even more powerful by these stupid glasses, which to me clearly have no legitimate, beneficial purpose.
