Are Advanced Alien Civilizations Rare?

These folks seem to think so..

Astronomers are using a technique to detect energy use as a sign of advanced alien civilizations.  Here is a bit more information on their methods:

Advanced civilizations harnessing energies on galactic scales (so-called Kardashev Type III civilizations) are expected to be detectable in the mid-Infrared part of the spectrum via the emission of significant waste heat products. A team of led by Dr. Jason Wright (Penn State University, USA) has already drawn up a list of several hundred candidate galaxies (culled from a total population of 100,000 objects) where unusually extreme mid-IR emission is observed. One problem is that although rare, this kind of emission can also be generated by natural astrophysical processes related to thermal emission from warm dust.

    This article assumes waste heat as a sign of advanced technology. What if there technology has reach the point of total mass to energy ratio. No waste. Antimatter to matter reaction is converted to 100% energy. No heat waste, just energy
