You say that as if somehow the trend for cross platform desktop apps to be ridiculously bloated bundles of browser overlays is new?
What major cross platform app isn't based on Electron or Tauri? Slack, Discord, VS Code, Teams, Notion...
The ChatGPT app on macOS is native. Same for the Gemini app.
You'd think Artificial Intelligence could be used to find a better path forward, alas.
Claude Code is uniquely stupid in that it uses React to power a non-Electron terminal app.
Though one would hope that they could leverage their advanced models to create native software per platform that can perform better.
