If you're in the "2 year old with unlimited power" camp, nothing can save us and everything is futile and we should all just eat drink and be merry for tomorrow the AI kills us all.
If you're in the AI-as-enlighened-buddha camp, the godlike AI will either save us all — or — just leave us alone to solve our own problems (while potentially locking out future godlike-AI development so we don't do too much runaway damage (eschaton, etc)).
