How smart are SETI@homers?

When a reasonable person fails to attain his
goal, he either abandons the goal or tries
a different method of attaining the goal.
An idiot is usually defined as someone who
responds to failure by doubling his efforts.

NASA is an ossified bureaucracy, but they are
not idiots. When their big SETI program failed,
they abandoned it. SETI@homers ignore their
failures and have little if any interest in
modifying their search method. Worse yet, they
seem to believe that some extraterrestrial
civilizations have been sending powerful
microwave beams toward the Earth for millions
of years. Why would the extraterrestrial tax
payers support such an effort? If we ever
receive their message it will say something
like: "Life is absurd. Have a happy suicide."
