There are much bigger things in this world to worry about. I bet you that by the time that this AI has taken your job, it'll have taken many other jobs, completely rearranging entire industries if not society itself.

And even once that happens you shouldn't be worried about your job. Why? Because economically everything will be different and because your job isn't that important, it likely never was. The problems humanity faces are existential. Authoritarianism, ecosystem collapse and mass migration of billions of people.

So if you really want to "prepare", then try to make a difference in what actually matters.
