Creativity in arts and creativity in engineering and other skilled labour are vastly different.

You don't need to be a Botticelli programmer to provide value to your employer because being famous or unique is not how programmers provide value. Programmers are paid for solving business problems. The variability of that is not going to dramatically increase due to automation.

Even today you can tell that mediocre programmers are earning good wages while mediocre painters / sculptors / actors are starving. It is not because they have been automated.
