> The most interesting thing about the apocalyptic sci-fi scenarios is that they show the fundamental irresponsibility and recklessness of many very important AI leaders. 

To me at least, it looks like a very cheap and transparent way of bragging and elevating one's self-importance. If we take a practical approach, then AI is just another tool that makes some jobs easier and more automated, which sounds about as sexy as inventing the mass-production of interchangable screws. An astonishing improvement for people who used to mill everything by hand, and absolutely critical technology for the modern world, but barely anyone has even heard of the people who made it possible.

Another aspect is the world that people like the Altmans and Musks come from. The wealthier someone is, the more detached they tend to be from the manual labor that runs the world. When your goods simply appear at your door after a few taps on an app, it's easy to forget that someone made them with their hands (especially true for high-end products), someone packed them, someone drove them to a warehouse, someone photographed and edited them, someone wrote the listing, someone packed them again, and someone eventually brought them to your door.

The entire physical world gets compressed into an app. From that perspective, it can start to seem as if the app is the world itself, and that if someone can hack the app, they can destroy the world.
