But a lot of what that technology does is reduce the energy cost of doing any particular thing - so naturally, we do more of it because it's cheaper, but for the same energy input we're getting much more. When calculations had to be done inside human brains, plus paper and abacuses, the cost - in energy - per calculation was huge. Now it's not, the cost is tiny. Even if energy becomes more expensive, you don't lose that advance. The same technologies we use today would work well with a whole range of energy inputs. Some would be easier than others, but most technological advances are, and have been, genuinely more efficient ways of doing things.
