It's bad for building your resume. Managers and employees are rewarded for popular thing. Popularity is mostly a function of novelty. So the (social and therefore economic) incentive structure is inversely correlated with choosing boring technology.

I see it as analogous to people are frequently rewarded for putting out the fire instead of preventing the fire.

Try to explain that part of an imagined "Agentic AI Everything" product being built would be cheaper and more efficient as a simple function call. Good luck!
