You don't need an equal replacement to lose your job, just a good enough and more economical one.

Lots of graphic designers lost their jobs or at least a lot of their work now that image generation models have gotten decent at rendering text. Now any idiot can whip up some advertising graphics at half the quality of a designer, but in 1/10th the time and 1/100th the cost (or even for free!). It doesn't matter that it looks like ass and makes no sense in context, they produced an acceptable result for a fraction of the cost.

Quality does not matter in the market, it never has. Whoever can produce the most slop at the lowest price nearly always wins. Yes, there are exceptions, many of them even. But not enough to employ nearly as many of us as there are now.
