I believe the tricky privacy and security issues around smart glasses (and other "personal" tech) can be navigated successfully enough by a thoughtful, diligent, responsive company.

Which is why I'd never touch a person tech device from Meta.

Their entire DNA is written to exploit their users for profit. In my judgement, they literally cannot and will never consider those issues as anything other than something to obscure to keep people unaware of the depth of the exploitation.
