What domains seem to be more employable in the industry after 5 years?

Currently, a few domains like NLP and computer vision are promising for great opportunities to work in the industry after a phd.

Whereas some other domains, like reinforcement learning, still seem to be only sticking to pure research in labs, and thus arent as high paying either.

What domains do you think would have high paying opportunities after a phd in them, 5 years from now?
