What I mean by this is that we’ve reached a point where you can see a Youtube video shot in 2017 and it’s not immediately obvious the footage you’re seeing is almost a decade old. In 2017 you would’ve immediately been able to tell a video was from 2009 just from the video and audio quality alone

Youtube often recommends me random old animal videos and it’s a weird feeling when you look at a dog in a video that looks like it was shot yesterday and then at the upload date nearly 10 years ago and realise the dog’s probably dead as shit
Of course, this doesn’t account for cultural temporal signifiers like someone making an Amogus reference or something but it’s still something I sometimes like to think about 
What I’ve noticed is that everyone says attention spans are particularly low and yet every video on YouTube is at least 45 minutes long and most over an hour. I feel like 10 or 15 years ago that would be exceedingly rare. Now no one can shut the fuck up and get to the point.
Its weird that the algo is pushing longer videos while the settings in YT let you play things at 1.5x and 2x speed.
