From the perspective of the God of Evolution, we are the unfriendly AI:
And of course, we're unfriendly to everything else too:
As to why we're not exactly like a paperclip maximizer, I suspect one big piece is:
DNA could make exact copies of itself, yet it chooses to mix itself with another set. There might be similar pressures on minds to prevent exploitation of blind spots.
As far as AI designers go, evolution has to be one of the worst. It randomly changes the genetic code, and then selects on the criterion of ingroup reproductive fitness - in other words, how well a being can reproduce and stay alive - it says nothing about the goals of that being while it's alive.
To survive, and increase one's power are instrumentally convergent goals of any intelligent agent, which means that evolution does not select for any specific type of mind, ethics, or final values.
And yet, it created humans and not paperclip maximizers. True, humans rebelled against and overpowered evolution, but in the end we ended up creating amazing things and not a universe tiled with paperclips(or DNA, for that matter).
Considering how neural network training and genetic algorithms are considered some of the most dangerous ways of creating an AI,
the fact that natural evolution managed to create us with all our goals of curiosity and empathy and love and science,
would be a very unlikely coincidence given that we assume that most AIs we could create are worthless in terms of their goals and what they will do with the universe. Did it happen by chance? The p-value is pretty small on this one.
Careless evolution managed to create humans on her first attempt at intelligence, but humans, given foresight and intelligence, have an extreme challenge making sure an AI is friendly? How can we explain this contradiction?
