So to be clear, you're saying that ALL the people that you currently know of who work at these companies believe they are actively working on, in your words, something that "...poses a potential existential threat to humanity"
Oh nevermind I get it. They're only intentionally working on building something that they believe will end humanity. Well as long as it's not intentional crypto-tier scamming, it's all good then.
I'm convinced. Consider my model of reality corrected. Thanks homie.
