There's also a lot of fear and anger about the AI tsunami these days, among certain user cohorts, and that's an amplifier as well.
On HN, personal attacks aren't allowed regardless of who's being attacked, and comments are asked to make their substantive points thoughtfully and not be cynical or snarky. Here's one guideline:
"Don't be curmudgeonly. Thoughtful criticism is fine, but please don't be rigidly or generically negative."
More generally, there are now literally trillions of dollars being invested in this madness/tsunami/whatever-one-wants-to-call-it, which means that it has now become impossible to follow said money so as to follow the conflicts of interests (it’s easy to assume a conflict of interest for a guy like Karpathy given his past and recent employment history, but I do think that Simon is more on the genuine side), so this is why that counter-reaction is now manifesting itself so chaotically, hitting left and right with not necessarily any logic behind it, which means that there are going to be collateral “casualties” during it all (such as Simon in this case).
