But literally everything you describe is worse outside of the browser.

My browser does a better job of retaining state than most of my apps. My desktop apps have clunkier auto-update than my browser. My browser apps auto-save to the cloud, my desktop ones often don't auto-save at all.

I'm talking strictly client side. I literally said "unless stored on a server", and let me remind everyone that "cloud" just means other people's computers.

(Also that "serverless" really means "there actually is a server, but you don't get to manage it".)

Desktop apps can save files and read files. That alone puts them miles ahead of any purely client-side app. As for convenience, most apps today auto-save stuff when you're not looking, but lack of that feature isn't a big deal for me - I started using computers some 25 years ago, so I habitually press "CTRL+S" every couple seconds without even realizing it.
