Don't extrapolate from present harms to future harms, here. The problem AI alignment is trying to solve at a most basic level is "don't kill everyone", and even that much isn't solved yet. Solving that (or, rather, buying time to solve it) will require political solutions, in the sense of international diplomacy. But it has absolutely nothing to do with "aligning corporations", and everything to do with teaching computers things on par with (oversimplifying here) "humans are made up of atoms, and if you repurpose those atoms the humans die, don't ever do that".
