I do think it will grow for a while... sandboxing with node/electron with wasm will become far more common. The sandboxing model actually delivers on a lot of what was promised with Java without having painful UI/UX constraints. It's a little more bloated that way, but works out.
Another alternative to electron is Carlo (which uses the already installed chrome and node for it's operation... I think this may actually surface more and more as a base application choice for cross-platform apps.
Today most of my time is spent in VS Code + Bash, Chrome, MS Teams, Hyper and Spotify. Most of which are electron apps, and the other the core browser they all use. I don't think it's the *BEST* choice for much, but it is *good enough* for most things.
