I'd fund science. Like all of it.
I'd fund solar energy, nanotech, robotics, cars that drive themselves and run on unicorn farts, Sea Lab, cyborg prostheses, atmospheric carbon scrubbers, that thing from FO3 that cleans radioactive water, cold fusion, FTL drives, super crops, and pretty much every non-military thing that would be useful. Or just create the Matrix so that none of the other stuff will matter because reality is then your plaything.
Why lament that you will never get to see the universe, or even much of this planet when you can jack in, and see everything and anything over the course of a greatly extended lifespan via your slowly decaying husk being augmented with various chemicals etc.?
How do you know that you aren't already living that way, in some crappier version that only gives you real freedom in dreams?
Or if all that is too much trouble, I'd just make Amazon very very happy and my mail carrier very very busy.
