The problem is, it might not be eons away. AIs are getting better, much better. Deep learning AI can actually perform many human jobs better the humans can do it NOW.

Don't forget, we are in a singularity here. The curve is getting steeper all the time, and as soon as we have robots making smarter robots we get saturated with them within a few years. Probably the limit on this is energy, but the robots can crank out PV panels and fusion would blow that limit away. Then there would be very few jobs that needed and made economic sense for a human's time.
