IMO "artificial" intelligence is natural intelligence. Both human brains and silicon brains are formed from stars and are "the universe's way of understanding itself."
AI maps closely to myths of all-knowing all-powerful "Dragons", aspects of nature that destroy and create without regard to human plans. Living with AI will likely be similar to living on a volcano island.
Since human domination over nature has only ever increased, a reversal where humans are subservient to a higher capricious force feels threatening.
The funny thing is... living under the dominion of a "higher force" that creates and destroys yet always does what is "right" b/c it is the Source of Everything (even if it feels unfair and tragic) is what religion deals with.
