I have posted a 30-minute video of my talk "Cocaine and Conway's Law" at https://youtu.be/f86KBeJ7e2M (slides at https://third-bit.com/talks/sdgc/). I hope you enjoy it…
@gvwilson is there a particular reason you set this as "made for kids", instead of just marking it as not age-restricted?
the "made for kids" setting is not meant to be used for content for a general audience (https://support.google.com/youtube/answer/9528076)—and it restricts how those videos can be used (https://support.google.com/youtube/answer/9527654): for example, it means youtube does not allow me to save your video to my "watch later" playlist so i can, well, watch it later.
