This seems like nonsense. The author claims that we're overwhelmed by the volume of content we consume and that's why we can't be creative. So the suggested solution is to do more work to consume content? That doesn't make any sense to me.
Also the recommendation to block content to curate your feed and not just scroll past it. Does he even realize what he is suggesting? That the user curates the social media feed to be more tailored and thus addictive. It won’t shorten just because you block stuff. The actual cure to that crap is to fill your day with healthier activities so that you’ll end up surprising yourself you hadn’t browsed Instagram today.
I find that it does shorten. Of course infinite scroll still happens but with a ruthlessly curated feed, it seems like after about 5-10 minutes of browsing there's a tipping point where relevance drops off a cliff. That's when I know to close the app.
(I open IG maybe 1-2x a week, FYI)
