I have a very low tolerance for UI lags in my text editor. I'm a vim user, but can't use macvim, since it tends to be laggy, for instance. I find the jetbrains IDEs to be painful to use for the same reason. python being slow is not a "meme," it's just reality. The performance issue for a text editor or other GUI is latency, which is a difficult problem even when you have more control from using a lower-level language. A dynamic scripting language with a garbage collector is just not going to cut it. not to mention python's demonstrated history of becoming unwieldy as project size increases. pythonistas either say, "it's not slow!", or, "it doesn't matter if it's slow". In some cases, it truly doesn't matter that it is, in fact, slow as molasses. But a text editor is not one of those.
