Yeah, you say that now, but when we get more power, you can all but guarantee we'll use more power.
Probably, we'll start creating climate controlled neighbourhoods or something, live in Sunnyvale Town, where it's 30c all year around!
Actually, I'm not entirely sure this is correct. There are other factors that would act as choke points. Portable devices, for example, and their batteries; you'll go out of your mind if you treat your smartphone as though power was infinitely cheap. Transmission/distribution infrastructure is another MAJOR issue...even if you wanted to ramp everything up to 465KV lines everywhere, there's only one company on earth that makes the transformers, the power cables can't handle it, and within the existing rights-of-way for transmission lines that much power would introduce problems with foliage (the safe zone around a line increases with the power it carries), and we'd likely see a repeat of the 2005 blackout on a regular basis. And that's just what I can list off the top of my head.
But even aside from all that...so what? Your point is like saying that cars that get good gas mileage are a bad thing, or that Moore's law sucks because it just means we can do more with our computers now.
