I'm glad Kurzgesagt is around.
They have done an awesome job. They have created quality content with nice animations and a soothing narrator voice. The videos are short enough and interesting enough to keep me hooked 'til the end. I can share their videos and quote them about important aspects of life. They even changed my philosophical point of view about life.
I think I have watched every video from them. And that nets them a reward - me taking part in buying stuff from them!
