I thought it’s a good question and I planned to answer by writing a blog post. Meanwhile… I don’t find it very easy to answer, but if I would put in a scale on one side my time investment and expenses (server etc) and on the other what I get out of it, it’s not very balanced. I know my videos have helped and made many people happy as I received many positive comments. But unfortunately I don’t see them bringing me many new opportunities or pushing me beyond my limits. I do enjoy creating such content very much. If I only got paid for it… In recent years I focused more on giving GLSL workshops and financially at least it was better. And since asking is free: I’m open for meaningful jobs and collaborations involving creative coding

ps. Art is meaningful and makes the world a better place.
ps2. And to stay on topic: writing programs in Kotlin makes me happy
