If AI turns out capable of automating human jobs then it will also be a capable assistant to help (jobless) people manage their needs. I am thinking personal automation, or combining human with AI to solve self reliance. You lose jobs but gain AI powers to extend your own capabilities.

If AI turns out dependent on human input and feedback, then we will still have jobs. Or maybe - AI automates many jobs, but at the same time expands the operational domain to create new ones. Whenever we have new capabilities we compete on new markets, and a hybrid human+AI might be more competitive than AI alone.

But we got to temper these singularitarian expectations with reality - it takes years to scale up chip and energy production to achieve significant work force displacement. It takes even longer to gain social, legal and political traction, people will be slow to adopt in many domains. Some people still avoid using cards for payment, and some still use fax to send documents, we can be pretty stubborn.
