To me it seems that AI is harmful, like the author says, for society, mostly because it seems that the direction where we are going is just to maximise profits and make a lot of money. If we remove "humanity" from the productive world, what does making money mean in the end, where will it come from? Because it doesn't look like the world is heading to: these huge corporations will now support you to be creative and live a free life with no stress and work, because AI is doing all that, it will just mean that they will optimise everything to make as much money as possible, to a point, completely disregarding our humanity. In the end some people will live in an "Elysium" like world, where the most of us will be living in some sort of dystopian underworld fighting for survival.
