I went down the rabbit hole mostly as an ideological thing. Everything I do with a computer that isn't video or shopping (so anything that has anything to do with being productive) is centered around the idea of navigating, reading and/or manipulating text.

Most tools today seem to try their best to destroy that experience. Emacs does not. My main gripe is that Emacs isn't enough of an operating system. I don't like having to leave. The thought of an expanded Emacs with a unified GUI centered around text is for me almost a wet dream.
