I don't disagree about the core CS fundamentals - 100% the same page. I suppose this really boils down to a difference in what constitutes "training/education".

Any $PROGRAMMER_TITLE worth their salary can learn a new stack for a project, because they know the fundamentals. BUT there's still a lead time on being comfortable with new languages, frameworks, problem domains, etc. It's this kind of time and effort that I am trying to get at when discussing companies paying for training/education. It can be worth investing in your people if your goals are longer horizon.

I don't think it makes sense for companies to pay for their employees to learn basic data structures or other "prerequisite" fundamentals, though. That would be a large investment!
