> I would much rather have to spend a few days to relearn a tool every few years and to get the benefit of that tool, than accept a lower quality tool just to avoid a few days work.

I've worked with engineers who studiously avoid configuring any sort of quality of life improvements for their shell, editor, etc. because they claim it makes things easier when they have to use an environment that they can't as easily configure, like sshing into a shared box without a separate user for them to customize. This mindset has always been hard for me to understand; not only does it seem like they're optimizing for the rare case rather than the common one, but it seems like they're actually just lowering the quality of their normal experience in order to make the edge cases feel less bad without actually improving them at all
