This is hypothetical - the glasses don’t fact-check what people say, they somehow detect willful deception, like people expect polygraphs to do, but with high accuracy. Would people welcome these, fear them, object on privacy grounds? I think it would be very contentious. Would people feel different if they only fed the information to the wearer but didn’t record or send it anywhere? What exactly would the issues be?
Can’t speak for anyone else, but every other word out of my mouth in the presence of these glasses would be an intentional lie.
I would start being overly honest and forthcoming about things I don’t currently bring up because doing so isn’t polite. Wouldn’t want to lie by omission!
