I work even if I don't have to. It's about using one's potential, if nothing else. In the grand scheme of things, I'm grateful for all the progress other people worked on to achieve before me and which I'm benefiting from, and I wish to do my part and leave the world a bit better for others too.

Probably the same things that my work funds currently but more/better!

Piano, music composition, hanging out with friends/family, and social work.

Basically the things in my life that I think actually matter to me.

I would do what I do now, but I'd not feel threatened.

I'd still code a lot. Just not software of dubious social value that's meant to make someone else money.

I'd go hiking a lot. I would also teach what I know.
