And I'm not luddite swearing by vi or something, I use VSCode and Idea, and have used Sublime for many years, Xcode on/off for some Obj-C/Swift dev, Eclipse for 5-6 years in the 2000s, and vim for everything cli/lightweight since forever.
Is the GUI tech what's supposed to be novel? I couldn't care less about that backend in my everyday editor use as long as the editor is fast enough. Which on modern hardware, even Idea is.
Don't get me wrong, it's a good editor still.
