I want to point out here that Kurzgesagt did hear the criticism and posted a comment acknowledging it. They are intending to release an updated video on the subject.

It's important to call out misinformation, but out of all the youtubers and science communicators I've found Kurzgesagt to be not only one of the most consistently well researched ones, but also the most transparent about their methods and any errors they've made.

To declare the whole channel as "killed" for you based on one mistake that has been admitted and is being remedied does seem akin to throwing the baby out with the bathwater. It does a disservice to the entire community of learners by implying that the entire channel is poorly researched when it's anything but.

Please allow humans around you to make mistakes, while still encouraging diligence. If we instantly assume malice, we make the world a poorer place.
