Again, we already have experience with a finite labor-consuming exponentially growing economy looks like. I don't know how this comment is a rebuttal, since it doesn't address any of the points I made.

Especially since it repeats a line of reasoning, whose premises clearly apply to labor, but whose conclusions are clearly incorrect in the case of labor.

"So the price of energy must continue to drop" simply does not logically entail from the preceding premises.
