But the profit-aligned corporations are made of people, as you say, and once the leaders are personally affected by the „deterioration of the ecology necessary for human life to persist“, they will seriously try to stop it. That, I guess, is the difference to how AI would behave by default. (And in the thought experiment that you quote, unlimited capabilities are assumed, so the deterioration can be stopped.)
I am not talking about sci-fi magic and unlimited capabilities. What I am saying is very concrete and obvious: profits are misaligned with long-term ecological viability. The evidence for this is very clear as well because the biosphere is now full of synthetic chemicals and their byproducts which were created by profit-aligned companies and corporations.
