I think, realistically the way Skynet happens is that the military abuses LLMs for warfare. The military is historically, and currently, incredibly irresponsible with technology. If we aren’t already automating killer drones and such, then we will be soon because “well our enemies are doing it!”

I don’t think that means that it’s gonna, like, somehow homogenize into some mega super intelligence. But we will have machines who are designed to kill, and do so without human input or alignment.
