I would wager we are very far from peak complexity, and as long as complexity keeps increasing there will always be opportunities to do meaningful innovative work.
1. We may be at the peak complexity that our population will support. As the population stops growing, and then starts declining, we may not have the number of people to maintain this level of specialization.
2. We may be at the peak complexity that our sources of energy will support. (Though the transition to renewables may help with that.)
3. We may be at the peak complexity that humans can stand without too many of them becoming dehumanized by their work. I could see evidence for this one already appearing in society, though I'm not certain that this is the cause.
