You seen any diagnosis signed by an accredited physician? I haven't.
Funny how on the one hand such a lot of people on HN are willing to drag this out in Musk's defence, but on the other hand when the same is attempted in defence of, say, Richard Stallman, they do all hasten to point out that he's not officially diagnosed.
Unless and until we see a diagnosis from a qualified medical professional, we have no evidence that Musk is anything but an asshole.
