It's an obnoxious form of discourse when someone says X and the response is "obviously you're lying and you really mean Y, which is terrible". By all accounts Dario sincerely believes that AI has the potential to substantially improve the lives of everyone; that's my view as well. And it might be wrong! In which case you should offer evidence against it, rather than making empty claims that your opponent is a lying liar.
