The point isn’t the resource consumption.
The point is the resource consumption to what end.
And that end is frankly replacing humans. It’s gonna be tragic (or is it…given how terrible humans are for each other, and let’s not even get to how monstrous we are to non human animals) as the world enters a collective sense of worthlessness once AI makes us realize that we really serve no purpose.
Its not replacing humans any more than a toaster is. 99% of people used to work on farms, now its 1%. People will adapt.
