I’m an ML and data engineering consultant, so whatever time I spend working is something my clients have determined they need enough to pay my hourly. Whether the market needs their products is tbd. But there’s not a shortage of demand for work in this space right now.

Oh yeah, I don't doubt there is a market. Most markets are artificial fluff just waiting for a breeze.
I’m not sure why the success of a job would be based on human need more than it would be based on what the market will bear. Assuming the goal is earnings. But maybe it’s more of a philosophical debate about the definition of success. Or longevity of an industry/skill continuing to be valued? But predicting that is largely conjecture, and everyone is gambling to a certain extent.
