I'm old enough to remember when people dismissed all the doom coming from these companies as "marketing". (A thing many of them have been entirely consistent about since GPT-2, or indeed earlier given the founding documents).

I know a few people around these circles; People like this are quite sincere about the risk, and that they think poorly of their bosses and how risk is being handled.

"Think poorly" is such an odd response here.

Like, if people were genuinely doing a thing that had such a large probability of killing all humans... they should all be in prison. Heck, vigilanteism would start to look compelling. I do not understand how somebody can really think "well this is likely to doom all of us so we need to get there as fast as possible because we are, without evidence, the most capable people of controlling this thing."
