There are two mentions of "reliab[ility]" (I searched for the first five letters to be sure I got other morphological forms of the word). It appears twice: once near the top, as a general goal, and once at the bottom, as part of the general goal. Nothing in between, like saying "we'll be using {less AI | more AI debugging | more human screening | magic wands | secret sauce} in an effort to improve reliability". So at least as far as this post goes, hardly even lip service. Given the number of botched updates reported earlier this year, that's astonishing.
