Well, with RAM being so cheap, why bother trying to trying to be memory efficient? It's not like OpenAI has an infinite pool of "AI" software engineers to work on this...
Oh wait...
- Apple: SwiftUI/AppKit
- Android: Jetpack
- Windows + Linux: Avalonia (C#)
Avalonia seems good so far. I couldn't do Qt because I can't deal with that qBittorrent look. GTK is aesthetically pleasing for me, but it only runs on Linux. Avalonia lets me target both of these UI-toolkit-less platforms with something native-ish. Flutter is probably good too, but I am using uniffi-rs and that doesn't generate Dart bindings AFAIK.
Would love to hear other options.
