Why we might be alone in the Universe

RE: Why we might be alone in the Universe

We went from spark gap Morse Code to digital spread spectrum in a little over a hundred years. We use DSS to help limit detection, along with encryption. Except for stupid shit like "I Love Lucy", we haven't radiated all that much, especially when one considers that it mostly bounces off the ionosphere, and decays at an inverse square law rate when it does leak through. The means of communication through space are rapidly evolving, and mitigate against detection via remote entities.

And just from the perspective of power usage, it is reasonable to limit the spread of any emission you make.

of course, there is also the question of whether EM radiation is the preferred method of communication.
