EDIT: reading your reply to sibling comment, I think I probably misinterpreted what you are referring to here so my below response maybe is replying to the wrong thing.

Regarding your first paragraph, Qt/QML performance is very, very good, memory use isn't insane (in my personal experience at least), rendering is solid 60fps and animations are ultra smooth. Maybe Lazarus is better, but not being a good tradeoff for the user, at least in Qt's case, just isn't true.

Regarding your second paragraph, I completely agree, it those are C++ developers using frameworks like Qt doing that. They're primarily web developers who are using what they're familiar with (JavaScript) to develop desktop applications. An Electron application is very different from a Qt application.

Even with QML, which uses JavaScript, the bulk of the Qt framework is written in C++, the declarative QML is compiled to a scene graph on load, the rendering is done in OpenGL and shaders, and any heavy lifting or performance sensitive code can be done in C++ (Qt makes it VERY easy to call C++ from JS and JS from C++). Typically only non-performance-sensitive glue logic is in JS. This is very different front Electron and Qt (even with QML) is still primarily a C++ framework.
