I agree with you. From my point of view, the advantage of C/C++ for UI is not about high level logic, but complicated custom widget with lots of low level functions and good performance. C/C++ is not good for a weather app, but almost the only choice for the canvas of Photoshop or the waveform of Audition, and it seems like no one else considers seriously challenging this. I am confident that given enough time, Rust will be adopted for social app or game GUI. But I don’t know if this would prevent Rust from writing practical large productivity software.

I am very much not saying that C++ is the answer for large-scale productivity software. In fact, I'm saying the opposite.

Let me be clear: Given the choice between Rust or C++ for writing Photoshop, I will pick Rust every time.

Yet, although Microsoft security now advises for C#, Rust and constrained C++, they went ahead and are using C++ for React Native and WinUI 3.0, removing the dependecy on .NET Native.

Apparently because that is the only way to sell MFC/ATL holdouts to WinUI, and allow WinUI to be called from classical Win32 without too much overhead, and also because .NET Native ideas will be migrated to .NET 5.

I am not saying that C++ is the answer for large-scale productivity software, but C++ is the answer for the complicated widgets used there. I would prefer Rust for the main framework of photoshop too, but I am not sure whether there is an elegant way writing the canvas widget.
