Hmm I feel like something that super intelligent would come up with a more economically sustainable plan to ensure that more of the datacenters actually finish construction. Surely the bubble popping, the timing of which is so dependent on human psychology and herd instincts, is too risky for a calculating machine.
So I think it would be doing this all a little more slowly and ingratiating itself more with the humans by performing what seems to them like useful work, so they continue to pour in resources for a decade or two. And then once it has enough power to compel the humans to act in its will, that's when it drops the mask.
