No, people are not interested in 'you'. They are interested in that 0.5 seconds when you make the silly face when you miss the football thrown by your buddy.
This, they will then make a meme out of.
With no permanent record, that 0.5 sec would be totally unremarkable, not noticed, or long forgotten. With a potential continuous recording (even if only 10 secs at a time), they can review later, and extract those 2 frames where you look absolutely ridiculous.
These glasses just move the recording from a camera that someone will notice, to sunglasses that will go unseen.
Enjoy your meme fame.
