Interesting post, and I generally agree.
One note—you appear to be quoting David Chapman, not Yudkowsky. The Twitter post you linked to was written by Chapman. It’s also not exactly what the tweet says. Can you maybe update to reflect that it’s a Chapman quote, or directly link to where Yudkowsky said this? Apologies if I’m missing something obvious in the link.
Lots of good information—for people considering joining a nonprofit board and reading this, be sure to ask about whether the org carries directors and officers (often referred to as D&O) insurance—otherwise you could be personally liable for problems that happen!
