He mentions the economic and environmental aspects of AI but I think dismisses them a little too quickly. While AI as a tool can clearly provide many benefits, the external costs (i.e. costs not directly born by the project but incurred by others/society as a result of use of the tool) should not be ignored.
And I don't see mention of the seeming expropriation of works without compensation by the AI developers and the as yet unresolved IP aspects of using AI. These are part of the big picture economic impacts but also have moral and possibly legal implications.
In short, I think there are reasons not to treat AI as merely a tool.
