I'm not arguing Qt is perfect; no software is. But you can't argue that a platform built on JS and the DOM will ever perform as well as a native toolkit unless the native implementor makes unbelievable mistakes, or we put a vastly disproportionate amount of work into the JS platform. If you really have a thing against Qt, GTK has a bunch of bindings too (including JS!); go wild.

Or to put it another way, if you can switch your stack and get a "few years" of progress, that actually sounds amazing.

(Plus, and this applies to Electron too, you're free to fix bugs in open source dependencies that impact your project).
