I’d say that teaching people mental tech, like the stuff from Parts I and II of this blog, feels like a bad use of time to the extent it requires me to do so directly, e.g. where I have to actually spend time doing teaching.
A large part of the reason being, that it seems like you can’t teach people things you don’t know (namely, they won’t be able to figure out a plan to save the world if you can’t). And, impact is highly superlinear with respect to ability to think well. (It’s more likely that I personally end up funding geoengineering that reduces global temperatures by 1-3 degrees C, than that all of the scientists/politicians/activists whose sole job is global warming, even taken as a group, manage to do anything similarly useful).
It’s also very hard to find people who are receptive to learning in just the right way, as most people have too much at stake in how things are to take the risk of, you know, being willing to redesign their minds (I’ve yet to find anyone who wanted to).
I do think, though, that it might be a decent use of time to set up some sort of school or camp that taught the tech in Parts I and II of this blog, if doing so took zero time in terms of upkeep once set up, and if I had enough money to do so after funding more important stuff to cap.
