I don't have a link and can't be bothered to look it up.
Also somebody called it a "woke Jordan Peterson lecture" which made me wonder whether somebody is doing the whole jungian "helping young people to self-actualize" grift but without the reactionary baggage. Won't be surprised there's demand for that.
I feel like there's a deeper problem here than corporations and IP law. A century ago my horrible screeching over a guitar might have been the best music people around me were going to get without a hussle of traveling to a music hall or something. Nowadays all of the world's best music is a button press away. Same with the other forms of art.
That's one of the things I like about ttrpgs. My friends can easily play much better games than stupid prototypes that I concoct in Unity, they can read better books than my half-baked short hard sci-fi stories. Sure, they might partake out of politeness and I don't judge, I've been on the other end. But when I'm GMing they have no better choice than to deal with all the stupid shit that I've came up with or at least until they've made AI GMs.
