Not sure if this is a troll thread or an inside joke but I will post anyway.
Among the people that I know or know of, the biggest net worths do not belong to the smartest individuals.
The biggest net worths belong to those that dumbly bought and held income generating assets over a long time span (decades) whether it be dividend stocks or rental properties. The only real brain power they require is to probably visually check 500 day moving average once in a while. They also seem to have unknowingly dollar cost averaged by putting in more money at regular intervals.
So to get rich you don't have to be smart - just have to have an iron willed patience and have above average tolerance for risk/drawdowns.
Then there's me running multiple trading strategies in thousands of lines of python/R code, doing literally dozens of trades a day, and a resulting net worth that is nothing to write home about.
