AI vs humans would last 5 minutes
I find the portrayal of AI to be outdated and unrealistic. Skynet losing is a pipedream.
The guerrilla tactics used by humans in the future are harmless against an AI that controls everything like Skynet.
The AI would be able to wipe out everyone with nukes, drones, radiations, chemical and bacteria. Humans can do nothing but succumb in that scenario.
The only possible retaliation I can imagine is through computer hacking, if any skilled hacker is still alive and able to physically reach a sensible terminal. And I don't know if the AI will actually lay idly vulnerable to such a move.
