Qt is still used, but I think part of the reason it is less used is that C++ isn't always the right language anymore for building GUI application.
That’s actually why we're working on Slint (https://slint.dev): It's a cross-platform native UI toolkit where the UI layer is decoupled from the application language, so you can use Rust, JavaScript, Python, etc. for the logic depending on what fits the project better.
