Just because you think you're the smartest person in the room doesn't make it true.
While not the literal morale of the story of Flowers for Algernon, it's one of the big themes, i.e. your beliefs and understanding of your intelligence and the world around you change drastically with your "actual" intelligence.

According to one (or more) of the annual Stack Overflow Developer Surveys, didn't something like over 90% of developers think they were better than the average developer?
My point is that I agree with you. What one thinks isn't always the reality.
The fact that reality is WILDLY different for two people simply based on how they perceived it is exhausting.
Also it actually sums up why I hate managing people. Everyone is the star of their own show, and managing them is about showing them all the other actors. It's exhausting.
