Ok seriously, reading over this more, yeah, it's total and complete bullshit.
Computers can't make truly novel decisions. It's physically impossible, like generating a truly random number. They can absolutely make unintuitive decisions, which is why they're so good at games like chess - they come up with strategies that involve moving the same piece back-and-forth a dozen times until a better option presents itself, something a human would never think to do. But those decisions are still explicitly told to the computer to be available choices by the rule-sets programmed into them. Whenever a computer "cheats" it's due to either 1) a faulty rule creating available choices unanticipated by the programmer, or 2) the rules deliberately being altered to include cheating as an option. But the computer doesn't know the difference between those options, and it cannot create new options whole cloth.
The claims here are that the computer saw eliminating the controller as an option, then sabotaging communications, and so on. The very nature of such choices couldn't be accidentally programmed in, there's not a missing semi-colon or an incorrect math symbol that leads to the logic of killing the operator to free the program. Nor can a computer arrive at that option as a novel decision, because again, that's not possible. So assuming such an event actually did occur (which I am dubious of, but we'll go with it), they had to specifically provide that choice. And once you do that... well, the event suddenly becomes a lot interesting, because it takes even the simplest of probabilistic algorithm to make that choice if it's available to them.
So the most generous read here is they gave a probabilistic algorithm simple, pre-set self-sabotage options with a direct if-then chain leading it to the next option in its toolset, weighted those outcomes in a way that gave them reasonable chances of being chosen, went "oh my, here's our headline to generate funding, just like we were shooting for!" when it does exactly what they expected, and then went back to assign those options negative karma points in War Crimes Simulator: 2023 Edition - Now With 100% More Tech Bro Bullshit.
More realistically? The entire fucking thing is made up.
This is pure fucking military propaganda.
