I think insanely rich is probably the worst thing on the list. How are you immortal and the smartest person alive and still broke? You should find ways to make a fortune easily oorr if you really want to change something you can use your power to actually improve the system in the long-term and not just profit yourself.
I mean yea that’s the plan. What are the other options? Force every countrie to stop producing instead to reduce carbon emissions that way? Wich one Sounds more realistic? And I feel like you assume that fusion reactors are dangerous because your comments about war torn countries. But it’s not possible to turn them into weapons. They run on hydrogen. And if they ever oberheat or something the magnets stop working and the reaction stops.
