Take a Minute by K'naan about the value of giving and epistemic humility lol

I recomend AISafety.com and, if you are looking for introductions in video/ audio form, I like this selection (in part because I contributed to it). 

None of them are that technical though, and given that you mentioned your math knowledge, seems that's what you're interested on. 

In that case, the thing that you have to know is that it is said that the field is "pre-paradigmatic", so there's not any type of consensus about how is the best way to think about the problems and therefore how would even the potential solutions would look like or come to be. But there's work outside ML that is purely mathematical and related to agent foundations, and this introductory post that I've just found seems to explain all that stuff better than I could and would probably be more useful for you than the other links. 

I think something like that could be great! I also wish learning about EA wouldn't be that difficult or time consuming. About your questions:

1. For the people who don't want to change careers because of EA, I think you can still share with them a list of ways they still can have a positive impact in the world, something like what PauseAI has. That shouldn't have a big cost and it would possible to expand about it later.
2. Adding to what you wrote, other ways they can still have an impact are:
   1. Changing their habits of consumption, like becoming vegan and reducing their pollution
   2. Participating in the community, like in the forums or volunteering
   3. Sharing the ideas and content, like the video/ course itself
   4. Small everyday actions caused by learning more about EA, like expanding the moral circle, the causes and having a more rationalist mindset
   5. Stop working or investing on risky things, like AI capabilities
3. I don't think so.
