Let's say for the sake of argument that the future posited in Trek is a fact. First Contact, humanity advances, the Federation etc. So by the time of the 23rd/24th centuries what things would you like to see different? I'm not talking big things like no more homophobia ect, but more little niggling details. Things that you look at in the here and now and just think, "Geez I hope by then they've gotten rid of this." I'll post one of mine in a reply by way of example.
