Haha! Oh that Elon Musk ... I'm actually a Software Engineer, and I majored in Artificial Intelligence back in college. Sure, there are merits to the fears, but sometimes it's all overblown. As long as programmers maintain responsibility, there won't be any possibility of Skynet or whatever robopocalypse in the near future haha I mean, who creates a war machine without a backdoor shutdown, right? Haha! It's all in how it's constructed. If creators don't think of contingencies for the possibilities of their creations, then they shouldn't be creating them in the first place.
Don't worry about long replies :) I'm guilty of those on a regular basis haha!
