What specialist skill/skills are you actively cultivating to assure your usefulness no matter the state of the world?
We hear all the gay commies thinking they'll be the poets and prostitutes after the revolution, but what real skills are you developing?
EDIT: incidentally i guess i know how to set up a large-scale greenhouse plantation, and care for and harvest a good few types of veggies, which is sort of a specialist skill in this day and age... but i'm not nearly as passionate about the stuff as the game dev.
