Not at DEF CON, no.
But the camera takes this to extreme anti-social levels.
Google's device also suffered from making the user look ridiculous, like a gargoyle out of Snow Crash, but at the end of the day most people had the same core issue with it as they have with the Meta glasses which is that people don't like the idea of being filmed in public, especially when the filming is somewhat surreptitious (since you don't have to hold bulky camera gear, or at least a phone-sized device to do it)
Of course you have the legal right to film people in public spaces in many jurisdictions, but you're likely to be socially ostracized for it (and IMO rightfully so).
I don't think that this can be the main issue, given how nobody really cares about security cameras in public spaces or all the cameras modern cars can come with, nevermind dash cams.
Someone filming/shooting in a park with a kit 18-55mm lens is fine. Swap that with a bulky 300mm or more and you are bound to get some questions asked.
A content creator casually shooting content in a mall is fine but if you start interviewing people, aiming your camera directly at them, it's at least common courtesy if not legal requirement to ask for permission.
Personally speaking, I wouldn't mind someone wearing these creeper specs in public but if they talk to me or if we eat at the same table, I would expect the courtesy of them putting the glasses away.
I definetely don't want a camera in there.
Not sure if such a beast exists. But due to Meta/Google screwing up with cameras, I may never get my display glasses.
But they will come and will get better. Apple is also supposedly still working on some and they'll likely try to get rid of the "camera issue". Or maybe they'll try to make it the new normal. But they already exist and there will be more of them in the future - with and without cameras.
But they look less stupid than Google Glass did and even if they didn't look stupid, people would still consider them "pervert glasses".
In fact, I think the more indistinguishable these types of devices get from regular glasses the more people will be upset by their existence. The less immediately obvious they are, the more you seem like a creepy pervert for using them when the core problem is people don't want you filming them without their knowledge or consent.
My fear is that these spy glasses will actually become indistinguishable from corrective glasses. I don't look forward to a future where everyone wearing any sort of glasses will be immediately suspect.
They don't care if it succeeds. They just don't want to lose.
The only thing I object to is the facebook association.
That "hilarious" and embarrassing misspeak or fall becomes a lot less so when it's a dime a dozen.
It's weird because it is (right now), not because it's some fundamentally weird thing ordained that way forever during the big bang or whatever.
Like, people don't like being watched when working, yet they'll sometimes outright forget they're screensharing. I know I do at least.
