Debussey in this world of intelligent people would bodybuilding as we know it still exist?
TO a certain extent. It would be seen as a way to maximize emotional well being by admitting that our appearance = still a factor linked to happiness for a normal humanoid, and that the maximization of happiness = the most intelligent goal one can pursue.
It would only be included if it could be mathematically proven that the time spent on BB would be the optimal happiness generating activity for that that time. This would require gathering data about the emotional effect of BB on each individual.
THe BB drugs used would be much better of course, and everybodys health would be monitored daily.
