social

Is it possible for social media to solve boredom without rotting our brains?

Yes, it is.  But it requires feed curation.  It requires a basic understanding that the algorithm responds to what you engage with, so if you're engaging with things that annoy you, you're going to keep getting things that annoy you.  Search for things that uplift you, nourish your mind, teach you something new, engage with those, and the algorithm will start showing you more.  I basically rigged my Facebook feed to supercharge my personal development, and it is great.  No doomscrolling, all growthscrolling.
