Again. 1. "Progress" does not need to imply "exponential growth in consumption of energy". 2. Even if it does, we may be many thousand generations away from hitting a ceiling.
It doesn't need to imply it. But from historical evidence it DOES imply it.
>2. Even if it does, we may be many thousand generations away from hitting a ceiling.
Not necessarily true. We don't fully know that. We're hitting ceilings with oil already. In the US peak oil already happened and we shifted to shale. We have about 5 more years of that. We're not sure what's left of middle eastern sources.
Other sources aren't ready yet, they're up and coming but we can't fully be sure technology will play out the way we want it to play out.
