What things will be different by 2050? I don't see electric cars or legalized MJ making it, sadly, do you?

Oh I think marijuana legalization (at least in the US) is now a foregone conclusion.. once the tax dollars start rolling in and people realize cities aren't going to collapse in a cloud of pot smoke.. state after state will legalize it.. and after 6 or 7 do so the federal government will simply drop laws against it as well. Most of the others don't seem likely to happen. Maybe only 20% of people getting married.. AIDS might get cured.. maybe. not sure what that forced sex business is about.
