I really like your idea because I have a very similar idea (though the focus isn’t just rationality). I’ve been planning to make youtube videos for a while, but have had difficulty getting myself to implement. I have outlines on topics I want to talk about already like you have here! The difference would be that I’m doing it more for myself than for those out there, because I don’t expect my youtube video to get out much. My biggest hurdle currently is video editing.
When I read your content, it felt like I was reading a news article. The only thing that might be an issue with that, is that you may want to have a bigger impact on your video. I felt like if you talked about something that made me critically think more, then it would be more engaging (and hence more appealing). Like, maybe explain Bayesian thinking and how it works since your target audience probably doesn’t know anything about Bayesian?
That was one of the reasons I wanted to make the youtube videos as well, to leave a legacy. Hopefully I can motivate myself to keep working on it. Let me know if you’re interested in sharing ideas or something. I don’t think we will conflict too much since my channel will idealy be all over the place with talk about relationships and whatever other random things that interest me.
