"This describes the most important scientific and moral challenge of our times", and you had never heard of MIRI/FHI/CFAR/LW in any way whatsoever, what are the questions you're going to ask?

"Why do you think so?"

They'll almost definitely be credibility questions;

Not in my case.

you want to read a book that's been edited well and comes from some kind of well-known intellectual expert on the topic being discussed, preferably one from very credible institutions like academia and government.

Oh, certainly not. Government is pretty much the opposite of a "credible institution" and as to academia, it depends on the field.
