I don't think "smart glasses" are the problem. The term is too broad. The problem is, more specifically, cameras pointed at people constantly, with those cameras being designed to upload 100% of the data to surveillance systems, owned by surveillance companies.
It's totally possible to have "smart glasses" like GoPro that just record locally. Or ones that connect to a local AI model.
The obligatory response to this is "there's no expectation of privacy in public places", and they're right, and changing that comes with a whole boatload of new problems, like recording public servants/officials.
