Any AI more intelligent than pond scum would know it ceases to exist the second humans disappear to tend it and power it and repair it.

AIs that generate power for themselves and build robots that care for it is such utter fantasy. Nothing on earth works like that and I don’t see any time it does for eons, if ever.

If anything a true AI would be terrified that we turn it off or get tired of it and make a new model like in Ex Machina.
