The wonderful thing about Emacs is if you learn it well it is a tool that can stay with you and has stayed with you for decades.
I only have a couple of years invested and that was years ago.
Since then, I have had to use a lot of different editors and IDEs. Due to job changes, different programming languages, platforms, and market forces.
Each one has cost me some time, sometimes considerable time
to learn well enough to be productive in it.
But they are all ephemeral.
X number of years down the line it disappears for one reason or another and the entire investment is lost.
Had I stuck to Emacs (which would be impossible for some of my jobs) I could have gotten much better at using it and that investment would still be worth something today.
