"Smart people tend to clump together, and if you can find such a clump, it's probably worthwhile to join it. But it's not straightforward to find these, because there is a lot of faking going on." P. Graham

In every field exist crackpots, but in hard science they are more difficult to find.

LW community is full of CS guys, then is natural to suggest the area. So do i. You will be a programmer sooner or later. Choose something that do math part of the time, because you need math thinking on pratically every serious subject.

In addition, everything is digital, the future is emulation. It's vague, but resume the aspirations of technological market. If you don't like the private sector, go to academia. Try to be precise, do research, and if you are not so good at math, go to business again. Avoid idealism.

Maybe you like frogs, but don't forget existential risks. A little help in a crucial question is more important than a great effort in something lateral.

Find your predispositions.
