I had an "I feel old" moment stood at the front of my classroom trying to figure out how to turn autoplay off on youtube (shockingly enough, after showing a carefully chosen video to my class I don't want it to start showing videos of Disney's Elsa). I clicked the gear icon and went through all the settings looking for the autoplay option. Then my TA pointed out the option is on the video itself. The UX is confusing because all the options there are specific to that one video but autoplay is global. I would have never thought to look there. Now it's right there where some sneaky kindergartener can switch it right back on when my back is turned... This is one small piece in the feeling that's been growing in me since leaving the tech industry that tech is hostile to me and the best interests of the children I teach.
