common, and that they are typically interested in contacting and
mentoring younger civilizations, how do you account for the lack of
evidence of them?
Your proposed scheme involved pointing lasers at various star systems
with earthlike planets and sending the AI to them just in case they
have a radio-capable civilization we haven't detected yet (or whose
signals haven't reached us yet). That makes sense because probably
the range of time within which a civilization produces lots of
energy-wasteful radio signals is probably limited, and if we wait
until we get signals from them to send our own signals back, it might
be too late -- they could have advanced beyond radio and stopped
listening to radio signals, they could have destroyed themselves, or
just fallen back to pre-radio tech. So if such civilizations are
common, they'd already have been sending us messages two hundred years
ago (or whenever) just in case we happen to have the right tech level
when the signal arrives.
From the lack of evidence I infer that one or more of the following is
more likely than your assumptions: (a) sentient life is uncommon, (b)
most sentient life is less advanced than us throughout most of their
history, or (c) most sentient life that's more advanced than us is not
interested in talking to us. There's no proof of any of these, but
they seem more likely than the idea that they're all over the place
and we've just been unlucky about detecting those ubiquitous signals
they're trying to send us.
