The Simons Foundation was started by Jim Simons of Renaissance Tech, someone who seemingly isnt actively trying to poison public discourse with his billions of dollars, which I respect. We need more Jim Simons types and less Bezos/Musk/Ellison-type narcissistic psychopaths.
Since May 2024 he isn't actively trying anything at all.
If you're curious about Simons, and the wikipedia page is not enough, I found "The Man Who Solved the Market" by Gregory Zuckerman an interesting read.
His foundations are still doing good work.
