> The cost-benefit of learning something new vs spending that time either learning more of what I'm already in...
That's a good point. But you also need to consider it from the point of view of the person sitting across the table. You might be very productive solving a problem in COBOL (to exagerate the point), but they are much more comfortable in Python/Vue.js and don't want to burden themselves with legacy ways. Because they can find someone solving the problem in the stack they want.
Totally. I hope I didn't come across as saying my reluctance to adopt new techs is JUSTIFIED. I absolutely need to do it to be any good, and even those techs that DO end up being flash-in-the-pan can leave me better off for learning them. I'm just saying any reluctance is UNDERSTANDABLE, not "correct".
