Agreed. I want more native apps, not less. I cringe when I see web apps that are slow, don’t take advantage of native API’s, and have a completely different look and feel from the OS. No thanks.
Web apps already dominate the desktop (aka Electron) and I don't see where they are better/equal than a native app (except maybe vscode that is closer than many others).
If you can point me why Slack, Teams, WhatsApp desktop, Telegram, etc need too much ram to render a simple list + chat and call that efficient, then I would believe you about web apps being good.
The difference is that people enjoy using Slack out of the box. JetBrains' products are intolerably laggy out of the box on unless one is using top-end hardware.
