Doesn't even matter if the goal is extremely high. Talking about exponential when we clearly see matching energy needs proves there is no way we can maintain that pace without radical (and thus unpredictable) improvements. My own "feeling" is that it's definitely not exponential but again, doesn't matter if it's unsustainable.
