I agree with you on the principles & morals, but frankly this reads as scolding - all he did was explain how this can be avoided, which is good context to provide to the public. There isn't some hidden message there where he's "dismissing concerns people have with AI" or he's facilitating "outcomes that could be used for evil or with racist intents"

His tweet doesn't rule out the possibility that he secretly has a malicious set of incentives, just like your handle doesn't rule out that you're a Communist spy sent to fracture the American psyche. Yet, its ridiculous. I feel like a lot of the world in 2020 is for some reason a hostile filter is applied ~99% of the time on the internet, and you _rarely_ see that in personal interactions in real life.
