As long as our hypothetical Blub programmer is looking down the power continuum, he knows he's looking down. Languages less powerful than Blub are obviously less powerful, because they're missing some feature he's used to. But when our hypothetical Blub programmer looks in the other direction, up the power continuum, he doesn't realize he's looking up. What he sees are merely weird languages. He probably considers them about equivalent in power to Blub, but with all this other hairy stuff thrown in as well. Blub is good enough for him, because he thinks in Blub.
Emacs is not just a code editor. It will change the way you approach programming. As long as you don't understand it you might (rightfully, I guess) compare it to just "another text editor, only with these weird commands". Some of the stuff that Emacs can do and the way it integrates into your daily activities, cannot be seen in other text editors, so you're not even expecting such benefits from the other tools or realize that they exist out there, in the wild.
This is the most pretentious nonsense I've ever read. Writing code is writing code. God could create for you the most perfect IDE to ever exist, with every feature you know you want, and every feature that you don't yet know you want. Tailored exactly to your needs. But at the end of the day, you're just going to sit down and write code in it.
All I see when I look at people who endlessly tinker with their setup, are people who are spending time things that aren't providing aren't providing value to their customers. I've worked with quite a few emacs wizards. Do they write better code than me? Some do, some don't. It doesn't seem to related to their use of emacs though. Are they more efficient than me? Some are, some aren't. Did they all spend a lot more time than I did to learn how to use their text editor? Yes. Did they all have to tinker with their text editor a lot more than I did to get it working the way they want it? Yes. Have I ever had a problem that I wouldn't have had if I'd invested all the time required to master emacs? No.
Once you get used to that model of using a computer, it feels crippling to use applications that you can't easily program in on the fly. It's the difference between having a full programming language and a bunch of buttons you can press, and it's for something you're going to be doing a lot for a long time.
Funnily enough, that's how I feel about Lisp itself: I love having a language I can program at runtime, at compile-time, at read-time (and, in a decent editor, at edit-time).
It really makes me wish that there were a decent modern Lisp OS. It'd need some solution to run Firefox and emulate emacs. Maybe when I retire I'll devote my remaining years to that.
Are they really wizards then? :^)
Same with the LISPs (which Blub is about btw) - Some LISP programs become unmantainable for people that did not write it, but without a doubt, LISP is one of, if not the most expressive language there is.
