Recently I watched a video by one Freya Holmér titled "Generative AI is a parasitic cancer". She describes her Youtube channel as "I do videos on tech art, math, game dev, and whatever else I want to project to your screens". Holmér has been devastated by that for-profit companies have stolen people's text, and that it is becoming more and more difficult to find--using common search engines--things by actual people and not "AI" slop, for example when searching for information about a file format. In the end, she has resorted to self-delusion that she can ignore current "AI" stuff.
This incident concerning 3Blue1Brown is another sign of this "AI" greed.
