Think about the practical aspects of AI "taking all jobs", assuming that happens before society is prepared to regulate UBI or other mitigating post-scarcity policies. People will still need to eat, wear clothes, be housed, etc.

People provided those things for themselves before any form of automation, and they can always go back to doing it again.

Unless AI is going to prevent farming the land and refining its resources, society will carry on at least with these fundamental economics.

At minimum, people will work to provide the essentials for people at the price point they can both afford the essentials and afford the time to participate themselves in the production of those essentials.

So don't worry so much about it because it's not going to benefit you in the short term, nor in the long term if your fears turn out to be reality(which I doubt, personally).
