I ask this seriously because I'm surrounded by teenagers regularly asking me these questions.

Why become a health worker, when the hospitals are going bankrupt?

Why work at a pool, when they are closing the pools?

Why become a teacher, when nobody is having kids?

Why become a programmer when code will be generated?

Why work in a restaurant, when everything will be a self-serve kiosk?

Why become a truck driver when the trucks drive themselves?

Why become an anything, when everyone is growing broke and old? Who will you sell anything to? Who will you work for?
