It’s hard to say since there are major security issues with that. I think it’d be better if we weren’t anonymous but we’re not really ‘there’ yet mentally and culturally and it’d be used for nefarious purposes.
I do often wish I knew who I was talking to for real because I’d have vastly different behavior if I’m talking to a 15 year old kid, a 30 year old redneck or a 50 year old doctor for example.
