It can take a while to fully form a position on something. A year isn't really enough for most people to see how deep the rabbit hole goes (unless you were that one CFO that OpenAI had that left after a year). Regardless, publishing a piece like this against a massive company is always a gigantic risk.
I’m not a current or former OpenAI employee and I can see from the outside that they’re immoral and unethical enough that I’d never work there in the first place. That’s what I was commenting on. This person is probably set for life, so you’ll have to forgive me if I don’t really take their “concerns” seriously.
