You don't understand my core premise that given finite lifespan and finite attention, one can learn only a finite amount of things. People have shit to do and they cannot fit one more responsibility into their calendars. Not to mention that it takes two to tango so if you want to be fun and interesting while sober, you also need to convince your friends to also be sober so it's not all awkward.

It's really difficult to square the circle that being sober improves your communication skills long-term yet somehow young people have worse communication skills and less friends that previous generations of alcohlics.
