If chess is a solved problem, think about skating to where the puck is going to be, an interest area a bit further away from relatively easier verifiability such as coding, math, and hard sciences.

Do you have any interest in digital humanities? Knowledge work where verification is still important but not as black-and-white as does the math check out, does the code run.

Do you have any interest in family history or genealogy?
