The printing press meant regular people could read the bible, which led to protestantism and a century of very bloody wars across Europe.

Since the victors write history we now think the end result was great. but for a lot of people the world they loved was torn to bloody pieces.

Something similar can happen with AI. In the end, whoever wins the wars will declare that the new world is awesome. But it might not be what you or me (may we rest in peace) would agree with.
