Things will always change, there will always be jobs. AI will be a tool to use, good robots will be expensive, cheap robots will breakdown, everything will require some form of sales, management, maintenance etc.
AI could possibly throw the world into a great chaos. We've seen financial collapses before like the great depression. Who's to say that something even more disastrous couldn't happen with a tool that's unlike one we've ever seen before that can replace labor a lot faster than any tool we've ever seen before?
Tools are never just tools: they also influence the change of society to a great extent and societies have breaking points. Sales, management, and maintenance could eventually be automated also.
Lots of people would have sworn a decade ago that creative mathematical thinking was outside the domain of a machine. Now look what's happened.
Regardless of how automated parts of society become, there will always be a need for someone to do something.
You should always tinker and experiment with new things, that’s where you find opportunity.
