I have an expectation that people I'm speaking with aren't filming me without making it clear that they're doing so. Anyone doing otherwise I consider a creep and would rather not interact with.
Do also note that people wear glasses in private settings as well as public.
I think you are very confused about what a reductio ad absurdum is. It is not a fallacy, it’s a perfectly valid form of argument (similar to a ‘proof by contradiction’ in maths), and it doesn’t seem to be what you mean here.
Your can't draw over it with a marker? What about the microphones? Will this still be the case in the next generation or in glasses produced by other manufacturers?
No, if you cover the light, it will refuse to take photos or videos. Who cares about the next glasses from another manufacture? We are talking about the current Meta glasses that just came out.
But aren't the lenses more obvious on these? Just looked at the Glass and I guess they are about as obvious as the lense on that but the glass stands out more for sure because of its design (which I loved).
