I've probably spent less than 50 hours total over 20 years on my emacs configuration. But it wasn't all at once. And now I just copy the .emacs file between systems. Tweaking it is maybe minutes a year now. If I want to do something with, say, Go, I just download the appropriate mode. The longest time spent was when I had a few bespoke languages at work that had no text editor support in any editor. I wrote some minor modes to support them, that was probably 10 hours total with most of the time on the first minor mode, and the rest flowing quickly thanks to the prior experience.

EDIT: For comparison, I've probably spent 100x that (if not more) on Linux configurations.
