I now believe that there simply is no mainstream academic or other field (as of today) that can be considered to be "the locus of relevant expertise"… - Holden Karnofsky

My sense is that factory farms do a great deal of damage to the world that isn't included in the prices of their products. This includes environmental impact and cruelty to animals. I know very little about the former; what I know about the latter mostly comes from a book by Peter Singer (note that Prof. Singer promotes the organization I co-founded, GiveWell).

Regarding (b) <nowiki>[</nowiki>"checking boxes I want to check for considering myself a personally moral/ethical person, which is related but not identical to trying for maximum expected positive impact on the world"<nowiki>]</nowiki>: every year, I want to give a significant amount to "charity" as conventionally construed, straightforwardly helping the less fortunate. I generally believe in trying to be an ethical person by a wide variety of different ethical standards (not all of which are consequentialist). And I wouldn't feel that I were meeting this standard if I were giving nothing (or a trivial amount) to known, outstanding opportunities to help the less fortunate, for purposes of saving as much money as possible for adversarial projects (such as political campaigns) and/or more speculative projects (such as work related to artificial intelligence). I think the best giving opportunities in this category are GiveWell's top charities, so I will be giving a portion of this year's donation there, following the recommended allocation.

I could tell you about my strengths and weaknesses. I'm creative and intelligent and able to rock the boat and do things that can create uncomfortable situations and then not be bothered about it. But I'm not the best diplomat, I don't have a lot of patience for being sunny and making people happy.
