Will a PhD be worthless 10 years later? Should I stick to the industry?

I have done some research in RL and have some problem statements which I would love to do a PhD on instead of my sde job. I also have the money to be able to go abroad and pursue it.

However I can’t make decisions solely based on interest and without giving zero thought about the future. Hence the confusion.

On one hand I feel like its a good idea to pursue this even from future prospects because AI research might still require humans many years later, but on the other hand im afraid that if AI does it all then would I be better off in the industry because I might be able to pivot to other kinds of roles and be more of a generalist?
