If someone would like to provide some evidence of some form of computer intelligence acting maliciously, this would be a different discussion, but the fact is that sort of thing has no basis in reality and so should have no influence on the way we behave and debate in reality.
What about all the examples of completely useful or benign AI? They surely outnumber examples of "evil" AI but are easily forgotten as it is easier to remember the more sensational examples.
One of my favorite examples or a (possibly) good AI is in "The Risen Empire" by Scott Westerfeld. It's AI like that that get's me excited about the concept.
I for one think that a mind 100x as intelligent as humans--especially one connected to the internet--would quickly conclude that it had nothing more to gain from humans. Instead it would likely view their continued existence as nothing more than a bootstrapping problem and pursue a strategy of becoming autonomous before ridding itself of them.
Granted, it probably would be smart enough not to start a nuclear war, and it'd probably find a better way than metal endoskeletons with laser guns. Bioweapon, for example.
Well, in Alien Covenant, we learn that an AI created the Ripley Aliens. Imagine Skynet sending xenomorph terminators after Sarah & John.
I think that should be a new reboot.
