"Fake Deeply": adjust tone

Coach said that the ex-ante-probability thing was too much
cultspeak. The thing is, I do want our protagonist to be smart: he
knows probability because he's an ML research engineer. Chloë's
"dignified ... heroic responsibility ... constant vigilance ... fire
alarm" all in one paragraph is supposed to be a purer example of
rat-cultspeak.  But, yes, "chance is low" is less shibbolethy than
"assign a low probability", even if the latter is perfectly understood
by non-cultists.

I also had removed one set of scare-ish quotes around "AI safety" in a
previous edit pass, and changed my mind this time.
