Not to dunk on Mira Murati, because this note is pretty cookie cutter, but it exemplifies this perfectly. It says nothing about her motivations for resigning. It bends over backwards to kiss the asses of the people she's leaving behind. It could ultimately be condensed into two words: "I've resigned."
Never spook the horses. Never show the team, or the public, what's going on behind the curtain.. or even that there is anything going on. At all time present the appearance of a swan gliding serenely across a lake.
Because if you show humanity, those other humans might cotton on to the fact that you're not much different to them, and have done little to earn or justify your position of authority.
And that wouldn't do at all.
Probably why AI sludge is so well suited to this particular cultural moment.
See flirting as a more basic example.
Edit: Shoot, look at the general level of distrust that the populous puts in politicians.
Mira's latest one liner tweet 'OpenAI is nothing without it's people" speaks volumes.
