I probably spend 1-2 hours per day watching content on youtube (and much of that is at ~1.5-1.75X speed)

I don't know what qualifies as "addiction", but it is typically where I get my news, where a web-series I watch is released, and where I learn about social justice issues important to me, through video essays.

I'm sure my consumption is very different from that of someone who watches 100 1-minute Tiktok videos per day, but I think it's worth at least questioning how this might also contribute to cognitive performance and mental health.

Though I think a big difference with short-form content is the autoplay functionality (as your sibling commenter mentions). I watch videos which are released by channels I subscribe to, and occasionally (maybe once a week) watch something Youtube recommends to me. So I retain some agency over my viewing habits compared to someone whose decisions are dictated by the algorithm, which also has an incentive to keep people watching as long as possible.

Are your habits typical though? Playing long form videos at 1.75 speed? I suppose once you start engaging at hyperspeeds, you're making it closer to short form compulsive consumption. It'd be like speed reading a book instead of letting ideas and thoughts form.
