Welcome to my first meta-video! Today we will be taking a break from physical science (It'l be back tomorrow) and entering the realm of computer science, with a YouTube video about impressions and the recommendation algorithm that has a self-referential updating thumbnail that tells you how many people have seen the thumbnail!

I also introduce the "CTR-Watch-Time Product" as a metric for video success, effectively the additional time YouTube expects to retain a viewer by showing them a thumbnail. It's an interesting metric when youtube is behaving normally, and for videos of similar length.

At the end, I go into some detail on the python script that's actually updating this thumbnail all the time. Warning: it's absolutely horrendous code…
