"I do think there is still room for many more doublings in efficiency for computers" I don't think our finite physicist is arguing that exponential growth can't happen temporarily, just that eventually we hit the boundaries of our petri dish. It's a challenge to economic models that sometimes deny in principle that the petri dish even has boundaries.

If the universe is infinite then that does imply that eventually the petri dish will be too.

  It doesn't, actually. The universe is getting bigger but the available negentropy, practically speaking, is not. A big, heat-death universe is not a useful resource to anyone.
