In the past, especially after WW II, there was real job creation till the mid 70s. Companies today can grow without creating jobs, but in many cases by eliminating jobs. I don't see this changing again. You are either a valuable hyper-specialist or a commoditized specialist.

Professional development is fine but it will tend to make you more of a generalist, and I have not seen any evidence that companies value generalists. I am not sure there are really good solutions here.
