Fermi's paradox suggests that there are little or no other intelligent

life should exist on a substantial fraction of planets with life because
natural selection broadly increases intelligence with time.  Here on the
Earth, for example, numerous mammals have a high degree of intelligence and
many of them could reach human intelligence with a few more million years of
evolution.

ahhh maybe try this definition of the Fermi Paradox - rather
than making up your own?  By the way, Fermi never called
it a Paradox! Morons did that for him -
Have a nice drream...

"The Fermi paradox is the apparent contradiction between high estimates of the
probability of the existence of extraterrestrial civilizations and the lack of
evidence for, or contact with, such civilizations.

The extreme age of the universe and its vast number of stars suggest that if the
Earth is typical, extraterrestrial life should be common.[1] Discussing this
proposition over lunch in 1950, the physicist Enrico Fermi questioned why, if a
multitude of advanced extraterrestrial civilizations exist in the Milky Way
galaxy, evidence such as spacecraft or probes are not seen. A more detailed
examination of the implications of the topic began with a paper by Michael H.
Hart in 1975, and it is sometimes referred to as the Fermi-Hart paradox.[2]
Another closely related question is the Great Silence[3]—even if travel is hard,
if life is common, why don't we detect their radio transmissions?"

Because the radio age *here* will last only about 200 years, if that.
Perhaps they are communicating with their current technology which
involves xordonic emission from rotating bars of molybdenum of at least
250 meter length?
