I think I've been able to pin down what it is that I like about #Emacs so much. When I first started using computers, I was using a TRS-80. If you didn't have a cartridge inserted, It'd boot directly into BASIC where you could program the machine directly. That wasn't a bug, it was a feature.

Modern computing seems to do its best to hide all that stuff away. Everything is treated more like a simple (albeit specialized) appliance, not a powerful machine that can be made to do literally anything you want. Instead, it's about what the various software vendors want it to do.

Emacs by contrast not only gives you all the tools you need to modify it in any way you want, but actively encourages you to do so. It feels a lot more like the computing systems of old. Perhaps that's not for everyone. There's a reason computers were so niche back in the early days. Most people just didn't care to learn what was going on under the hood, and that's valid. There's something to be said for a tool that just works effortlessly out of the box. Also, to be clear, you don't strictly speaking need to dig into the internals to use Emacs, but I prefer for my technology to serve me, and I'm willing to put the effort in to make that happen.

That's why it's a good fit for me.
