Exactly this. Javascript frameworks allow overlap. I'm using the same tools and language to create a UI. Don't get me wrong I like QT apps and still tinker with them periodically. I will probably use them more once Go finds a way to make truly portable UI applications.
I guess that's cool if you mostly do web stuff. But there are tons of developers that use Python/C++ for embedded systems, OS, data science and other things that could make the same argument for Qt.
