We went from an agricultural economy to a tech economy and still have low unemployment. Jobs will change, which jobs will be needed in the future versus today will also change. Being an “influencer” wasn’t a career choice 10 yrs ago and the world has survived without calligraphers. I’m sure Hollywood hires less physical model makers than 3-D coders. Shoveling coal into a steamship isn’t a good career move these days, but biofuel may be. Things always change and the future is never what we expect.
