Let's actually talk about the "AI destroying the world" thing. One specific apocalypse scenario is the "paperclip maximizer" problem. The scenario goes that a super intelligence is tasked with maximizing the number of paperclips produced by a company. Because of a thing called "instrumental convergence," the AI kills all humans to prevent them from shutting it down, then it destroys everything else strip mining the Earth, etc.
Basically, the intelligence doesn't understand the actual goal of helping people hold paper together and therefore calculates intermediate goals that violate the *implicit* goal in order to fulfill the *explicit* goal.
The thing is, that's just capitalism. The whole AI scam is an example of this, where maximization of quarterly profit is an explicit goal and "destroying human civilization and most life on Earth through climate change" is a side effect of the "build as many datacenters as possible" subgoal.
Capitalism has been an apocalypse manifesting malicious intelligence since we figured out that burning fossil fuels changes the climate, back in 1824.

As noted by @cstross a long time ago, corporations are just hive minds with non-human goals, we've been living in slow-motion paperclip-maximizing scenario since the dawn of Industrial Revolution.
