I could not disagree more.

Space on disk, I have plenty. But the Electron version of many apps feels slow, sluggish, and it takes time to open, it takes time for every click to respond, it is the runtime cost what matters the most.

You say it is irrelevant? It makes a computer in 2026 feel just as fast as a computer from 2001, doing similar tasks, while the computer from 2026 is thousands of times faster.

And I definitely run more than one app at the same time.

This 300MB is the bare minimum used by these apps, in my example just an API tester. A simple "chat" app like Teams, Slack, or Discord wasting so many CPU cycles and so much memory is to me something that should feel like collective shame to our profession. Maybe that's why you disagree with me.
