Now here, surprisingly, is a wonderful and very straightforward account of the differences between Zuckerberg and Musk, which, as is pretty obvious, are really just differences between artificial narrow and artificial general intelligence: Zuckerberg and Musk are talking about completely different bodies of knowledge, one almost immediately, and one many years away. And Musk is very forward looking, 15-20 years away before it's REAL, but it does have to be dealt with now, including ethical regulation after learning deeply about it, because it's the greatest force in the world. And even in Zuckerberg's time, with artificial narrow intelligence, there are three specific items (the same things you already know, ad nauseum) which are very pressing, and need to be dealt with effectively now, including potential regulation, in the US as well as all over the world. Well done.
