You're not wrong, but users' UI/UX experience is already aligned with web apps. QT is weak on the web side, and with C++, there are too many things to worry about.

Precisely because I don't write it directly, I think what I need is not C++ but JavaScript. Thread safety and verification responsibilities in C++ are, in my opinion, the biggest bottlenecks in the age of AI development.

I'm tolerant of the brief pauses caused by JavaScript's garbage collector, but users are not tolerant of crashes. That's the key.

And while the core engine should be in Rust or C++, the code presented to the user? Yes, I think Electron is the right choice. The reason is that it's a familiar UI. If you present an unfamiliar new UI, users have to relearn it. But web UI is already familiar to most generations. From this perspective, I think Electron is far better than C++ in terms of design. I don't believe performance always wins.
