Why aren't they building Dyson spheres?

  That is a really good question. The thing is that if they are powerful enough to actually do that, perhaps they have come up with something better? I mean there could easily be a couple 1000 years between us, which means that the difference is at least as great as us and the Romans. The Romans might very well question why we weren't breeding more horses then, since we have such a huge need of transport and horses are the best way to do that.

  Maybe it turns out Dyson spheres are a bad idea for some reason? Maybe Dyson spheres are out there, but constructed in such a way that they don't look obvious to a distant observer? Maybe the idea that advanced civilizations exponentially consuming energy as per the Kardashev Scale is a flawed and anthropocentric premise based entirely on what we know of our own civilization, and a lack of observable stellar engineering doesn't necessarily mean a lack of advanced life?

  Maybe there's a lot of lower hanging fruits in the galaxy energy-wise than building Dyson shperes.
