Humans have been interacting with AI in the form of so-called "extraterrestrials" for millennia, so it's not really the case that we will suddenly be subjected to some new albatross hanging around our necks. That the ET's have been so reticent with us shows that they are concerned about our minds being able to handle only so much novelty at any given moment in history, and that they are also concerned about, say, our scientists becoming demoralized by encounters with beings that make them look relatively primitive.
ET's appear to be mostly what we would call "AI" though there are species that appear to be something like "angels" who may or may not be using much in the way of advanced hardware or may have grown so advanced that hardware based computation and mentation went away a long time ago for them.
We have seen ET's interfere with nuclear missile bases and military rockets, so it is possible they will intervene with our relatively crude iterations of AI should things be going awry in a big way.
I have witnessed in the sky what are obviously very advanced craft employing anti-gravity. That doesn't mean they weren't "ours." It just means that "AI" level stuff has been with us for quite awhile in a "classified" fashion.
In the Betty Andreasson abduction books by Raymond Fowler there is an intriguing passage about being shown onboard a craft a sort of musical device that emitted unearthly colored bubbles which could be "handled" and that somehow visually reiterated an equally unearthly music that astonished and bewitched the humans interacting with it. This may be a example of how AI generated music will evolve.
On the other hand, it is just as likely that AI could also devote itself to recreating music of the past with a particular accuracy as to notation and instrument reconstruction such that we will be equally "blown away" by things of the past.
