I think if they ever get good enough that a lot of people are wearing them, a lot of companies will put rules in place to keep employees from wearing them at work.

Restaurants, hotels, and other service industries don't want their employees posting video of insane customers to their personal TikTok profiles. Any company with any sort of technical or financial or medical data won't want employees to be able to take photos or video secretly.

I could see companies even attempting to ban them for customers. Like banks, airports, stadiums or other areas where large crowds of soft targets would gather. Schools to protect the security and privacy of children. It's one thing to go in a record with a phone; that is visible and draws attention. Being able to record completely in secret will be unappetizing to many (except when the government does it, of course, no one must question our police).
