This is an individual solution to a systemic problem. On a personal level, it is possible to solve such problems, but generally no, the ship has sailed quite some time ago (I personally think cars are to blame).
Even if you do it, you are still swimming against the current.
The problem with Electron is not that people choose it over native tech like WPF or SwiftUI, they choose it over nothing. Without Electron tons of cross platform apps simply wouldn’t exist.
I think macOS suffers the most since it is not that hard to port an iOS app to Mac, and Linux benefits the most.
The issue with JS is that each page gets its own execution context so they don’t share any memory. I am actually curious what does the WebView do to save on RAM here?
JavaScript frameworks/libraries are very rarely the problem, Electron just has to bundle Node, V8 and Chromium (granted, V8 is deduplicated).
Electron apps are hungry for RAM, but in practice it is close to having a heavy tab active. The thing about browsers is that they are pretty aggressive at offloading inactive tabs but Electron apps never do that.
I don’t really think AI would help much with the gaps related to the actual game design. It should allow for faster feature development, adding QoL, etc, but you need the actual game part coming from you.
Links with lots of data in them are really annoying to share. I see the value in storing some state there, but I don’t think there is room for much of it.
