I should also add that people who advocate for simplicity primarily do so because they want to solve bigger / more complicated problems, but the complexity level gets in their way. People who don't see the existing solutions as overly complex are content to stay at their current level and have no vision of solving bigger more difficult problems. They think they are already working at or near the peak of human possibility.
