  For more than 60 years, the predominant SETI search paradigm has entailed the
observation of stars in an effort to detect alien electromagnetic signals that
deliberately target Earth. However, this strategy is fraught with challenges
when examined from ETs perspective. Astronomical, physiological, psychological,
and intellectual problems are enumerated. Consequently, ET is likely to attempt
a different strategy in order to best establish communications. It will send
physical AI robotic probes that would be linked together by a vast interstellar
network of communications nodes. This strategy would solve most or all problems
associated with interstellar signaling.
