If alien species limited themselves to entertainment for such a long time, then where are the broadcasts from other solar systems?
On the other hand, recent studies apparently hint that things like electrical and gravitational constants may not be the same everywhere, so maybe they don't transmit their signals with light.
One more thing is that the argument that the age of the universe combined with its propensity to make life means there must be some intelligent life can also be applied to the probability that some intelligent life will wake up and save themselves from such a bad fate, as the author hints in the last paragraph. It doesn't mean all species get caught in that trap and never escape, it just means it's harder to become a species that saved itself from the perils of materialism, loss of social justice, and falsehood.
One reason I've read about is that when you consider humanity we were only broadcasting radio communication for a sliver of our history before we started using buried cables as a way to facilitate communication. The theory is that other civilizations would figure out the same thing and there is a limited window of time to intercept their radio communication.
