I am not a fan of String Theory, but as far as fringe science theories go, String Theory is probably one of the more innocent ones. If you are going to pour money into a fringe science theory, I would much rather it goes to scientists trying to discover some properties of the universe which may or may not exist (and probably doesn’t exist; lets be honest here), than many of the awful stuff which exists on the fringes of social sciences (things like longtermism or futurism) or on the fringes of engineering (a future Mars colony, AI singularity, etc.).
