But much like Linux itself was in the Windows 9x era, it is a gravity well for your attention, and you will want to do more and more with it if you can.

For example I have been using emacs for more than 20 years and only recently I got into the habit of actually running shells from inside it (it is very convenient, but just opening another terminal is an habit that is very hard to shake).
