the drake equation is a joke...it is the intellectual equivalent of a fish in the ocean searching for advanced civilizations, for a single minute, by looking for indian smoke signals, under the ocean, 500 years too late...
how long did it take humanity to develop long distance detectable communication? first radio signal was like 120 years ago...since then we have developed and we are now using things like quantum radars to get information that seems to be travelling faster than light...in 100 years I bet none of the inferior and detectable forms of transmitting data will be in use at all...just like indian smoke signals...
it is such a short period of time to look for smoke signals or radio waves that humans looking for current human tech equivalent signals in space is the same as trying to hit a bullet with another bullet by firing in random directions and not knowing if the other bullet will be fired at all...
drake was a nut sucker
