AI is a threat but question arises to whom and how? I mean it's clear that intelligence exists almost everywhere in living as well as non-living form. Sophisticated processes of the Universe are intelligence.
The "threat" that AI poses is that one day it will sprawl out of control and since it's artificial and in future it will be autonomous too and since it's "intelligence" it will be governed by precise mathematical and logical rules, it has a potential to create own its own new world as if you can really see everything is math and everything is logic in this world.
The main problem is math and logic doesn't understand human emotions and value and values in general for exmaple, square root of 16 has nothing to do with preservation of forests.
But if we try to add human emotions in the mix there's a good chance it will jeprodize everything just with more precision and speed as a normal human would have.
I believe there's only one way to understand what AI has to promise, lets keep our fingers crossed and see what future holds.
