There is a type of AI that puts two AIs against each other (GANS).
One tries to forge content (pretending to be original) and second tries to detect if it is real or forgery. Say for example you take original Picasso paintings and then an AI learns how to mimic the style and submits its work to another AI that verifies if it is an original or a fake. You repeat this enough times both AIs get better at doing their job but eventually, the fakes start to very closely mimic the originals to the point even humans can't tell the difference.
Quantum computing can take this to the next level and we could have AIs that can become their own Mozart.
Really fascinating, but when you start looking at AI that is smarter than us by a factor of 1,000, you really got to start considering Skynet scenarios. Right now we don't have the technology or the algorithms.
