Biotech! (witness the virus problem that we have known about for a while now, and did pretty much nothing about) Energy generation! Energy storage! Space exploration! New materials!

I feel like so many fields have fallen behind, because of the way incentives are set up. It pays better to be a banker, or a lawyer, developing antibiotics isn't profitable enough, it pays better to work at a company that gathers data about people and pumps advertisements to them. It's rather sad, really.
