Similarly, many people don't like learning new tools, and don't like changing their behavior. Especially if it's something they enjoy vs something good for the business. It's 2025 and people will have adamantly used vim for 25 years; some people aren't likely to change what they're comfortable with. Regardless of what is good for productivity (which vim may or may not be), developers are picky about their tools, and its hard to convince people to try new things.
I think the assumption that people will choose to boost their own productivity is questionable, especially in the face of their own comfort or enjoyment, and if "the business" must wait for them to explore and discover it on their own time, they risk forgoing profits associated with that employee's work.
