I want to know what you would be excited to see covered on the channel.
I'd especially like to know what videos you think would be optimal to make according to an optimization target you specify. It's more effortful, but more useful, to answer that question instead of just "what would be good video topics?".
Answers that go the extra mile and explain their reasoning in detail will be especially appreciated.
That said, I also welcome answers to the easier question "what would be good video topics?" and without much argumentation.
(Cross-posting my comment from the EA Forum):
Considering how awesome your video on Prediction Markets is, I think it could be a great idea to make videos about some other institutional innovation ideas that are popular in the rationalist world -- charter cities / network states, alternate voting systems like approval voting and liquid democracy, and so forth. (If you want to take things in an even more political direction, you could produce animated versions of the Bryan Caplan arguments for open borders or YIMBYism.)
For some more traditionally rationalist / EA media ideas, here are two of my comments on some previous threads about the idea EA documentaries.
Craziest idea: make a video about HPMOR -- either a movie-trailer-style animation, or a longer more traditional youtube-y style summary of the early parts of the story, and hope that this works as a short hook to get more people reading the whole thing? Thus leveraging the amount of rationalist content you imbue per unit of animation effort. (I feel like the idea of video-as-hook would work well for HPMOR and other works of fiction, versus with other EA / rationalist content it is better to stick to "video as summary of the key message".) Idk about the copyright issues here though.
On the subject of fiction, how about illustrating some much-shorter-than-HPMOR stories from the (allegedly slim) pantheon of great EA & rationalist fiction works?
As for why I think these are good ideas / what you should be optimizing for:
There is a natural tradeoff between making videos that draw in lots of new viewers (for instance, videos about aliens!) vs making videos that aren't as viral but communicate more of the information that you truly want to impart (for instance about futarchy or longtermism). So you want to have the channel strike a balance between those two things, including by alternating between videos that are more viral-oriented versus more education-oriented.
For education-oriented videos, I'd be thrilled if you made some more videos about institutional innovations, but that's just my personal hobbyhorse because I think it's underrated within EA. The more obvious direction to go for education videos would be to basically just adapt the 80,000 Hours content into a series of videos. (Some of these could have viral potential, of course. Imagine a video about how you can do more good for the world as [counterintuitive career path like AI safety programmer or etc] than as a doctor --make sure to mention that fact about how the number of US doctors is essentially capped by protectionist regulations! That would seem like a very controversial take to most normal people, IMO.) Anyways, personally I think the goal of the educational videos should be communicating the core EA / rationalist worldview and thinking style. (Rather than, say, CFAR-style productivity tips, or object-level education about detailed EA issues, or random mind-blowing ideas about quantum mechanics and the universe.) I could talk about this in more detail if you are interested.
For the virally-oriented videos, it's presumably more about just figuring out what's going to be a big hit. Hence my thought that it might be good to recycle the greatest hits of the EA/rationalist movement, especially catchy fiction which might adapt better than abstract ideas. Although I certainly don't know anything about growing a youtube channel to 100K subscribers, so all of my ideas about the viral side of things should be taken with a grain of salt!
political is popular, especially if you can focus on policy suggestions error check as honorably friendly to people hatewatching. keep in mind, a lot of people expect most people to be lying when political topics come up, and you aren't going to get through to those people, but you can try to suggest things that they can tell aren't dangerous for their friends to hear, they're just disagreed with.
