Why have the brain rot apps installed at all?
Can't uninstall the browser, and occasionally it's needed for legit reasons. I quite literally can't resist drifting towards mindless scrolling apps, though I know that's hard to fathom for some people.
I think it's not the apps are brain rot.
It's the content available on platforms and the way how you navigate inside the app. You can watch various content on YouTube for instance.
