I think it's a little too niche, and as embedded processors get more and more powerful, we'll just see the same trend of doing all UI in a browser instead
You don't need powerful microprocessor for UI. Just some sort of connection. WiFi, network, file system. Then UI can run in browser on tablet, desktop...
Care to say why? I ask because that's what I use at work: C++ and Qt
Yes, I'd prefer Rust and Slint/Tauri.
But like a prostitute I don't do what I love, I do what pays the bills.
