I'm 40; you're fine. I put down Instagram last year, and I never even think of it anymore. Your mind evolved over millions of years, "short form content" is not going to rewrite that. Once you delete that stuff off of your phone, your brain will immediately free up that headspace, like Instagram never even existed.

I don't know about my concentration. I've got more non-negotiable responsibilities now, so I have less time to work on things, but I work on them harder, and I take advantage of the off time to let solutions bubble up.
