It won't break the world, but it's warranted that it will break the world of people doing labor and getting paid for it. And when you think of it, even being a mediocre (or even moronic) investor is practicing a form of labor, so not even capital ownership is safe in the long run. And yes, generational wealth is a thing but there are tides that slowly shift wealth from A to B (e.g. from USA to China). Have a machine smart enough with even a sliver of motivation (intrinsic or extrinsic) to get some wealth for itself, and just watch what happens...
