The discovery of several thousand extrasolar planets shows that the emergence of life on some of
them is predictable and expected event. It follows that with a certain probability can (and should) exist
civilization, outpacing terrestrial one in its development. This further aggravates the paradox formulated
by Enrico Fermi: why there are no observable manifestations of activity of supercivilizations if life is not
a unique phenomenon in the Galaxy and in the Universe? It is often assumed that the absence of such
manifestations caused by that supercivilization quickly cease to exist ("die by suicide"). However, this
view is ungrounded. On the contrary, consideration of demographic, energy, heat, radiation and
mutational genetic (adaptation) barriers to extensive development and distribution of Earth-like
civilization can solve the Fermi paradox otherwise, in a constructive way. Earth-like civilization rather
quickly moves on to another - intensive - development strategy, in which it displays hardly noticeable for
the remote external observers.
