Update
of April 18, 2004
Yesterday, I attended Cal Day at the University of California at
Berkeley and heard Dan Wertheimer give an overview of SETI, and in
particular, UCB's contribution to it, including seti@home. From
Dr. Wertheimer's talk, apparently nothing at all has really changed in
the basic quest, the signal criteria for announcement of a successful
hit, or the protocol of the latter in informing the world's
governmental authorities and the public. There was an
unemphasized comment, however, that interest had been added, to the
program, in recognizing signals that might be seen as related to living
organisms of lower
intelligence/complexity/egoism/whatever than humans -- maybe even some
without doctorates ;-) -- and even a hint that "signals" from entities
that SETI philosophers might be resigned to categorize as
unliving. However, no criteria of signal
complexity required for announcing any of these categories of lesser ET
intelligentsia were put forth.
During the question period, I asked whether the "I" in SETI still must
stand for 'intelligence'. Dan admitted that he was unhappy with
this word. As he had described the huge number of people enrolled
in his seti@home -- and of course, the huge sector of the public who
have been told those green things out there with radio transmitters had
to be intelligent -- I was nasty, and classed the SETI effort as a
scene of "false advertising". . .but with a ';-)'. Well, y'know,
this game is propounded worldwide as advancing SCIENCE. . .and
scientists are supposed to be above playing games
with the rest of the world, right? Or so they would have you
believe. We know, of course, of others who have become mired in
the the delusional quicksand of the concept of intelligence (a
subjective notion) -- Arthur Jensen, Mensa, etc. It correlates to
the mathematical concept of complexity when applied to
objective-information processing, but it's not at all clear in what
manner, and the mathematics of complexity is still very incomplete.
I also noted that Dan did try to play
down Frank Drake's infamous equation of factors of unknowable values
and unknowable interdependence. But this equation was brought up
in "Contact", the movie, so of course, a member of the audience had to
throw it up for discussion. That's really what SETI is --
entertainment. . .and I'm the Grinch.
My interest here is not in making any ethical accusations as to the
funding of SETI infrastructure and activities, though those that thrive
under the auspices of UCB can be seen as questionable use of the
presently very scarce educational resources of the State of
California. But 1) educational activities have funny
institutionalized mantras we keep paying for under all circumstances --
you know -- like repeating the words of Shakespeare, Chaucer, etc.
every generation, or banging heads every year in football practice; and
2) yes, each improvement in the technology used for SETI does advance the
state of the art of applied electronics, etc. I just think the
intellectual integrity of this highfalutin pursuit, at the level of its
very essence, is no better than 'Mommy, I know how to talk to
angels.' And yet, it is carried on by sophisticated adults,
including a supposedly enlightened doctorate at yoonyversities.
And then there is the issue of How long do we keep playing this game
without any success, i.e., with ' I ' = intelligence? SETI, at a
sophisticated technicological level, now has
quite a few decades behind it -- with nothing, really, but brute-force
steps in attempts to achieve its goal. Amusingly, a member of the
audience asked whether SETI hadn't maybe, by now, proved the null
hypothesis of its quest: No smoking clothes by now might
have proved there aren't really any emperors out
there. Ah, but Daring Dan was not ready to throw in the towel (to
cover the naked dark matter where the ETI should've been). . .based on
such things as the fact that it takes a while to cover an infinite
number of possible transmission frequencies. . .and, I suppose, an
acceleratedly expanding universe, the limits of which one can never
reach no matter how one fantasize (Hubble trouble). So, if you're
headed up to Lassen National Park and its adjacent natural lava beds,
you better get used to seeing an ever-increasing pox of those little
unnatural inverted pimples around Hat Creek -- an infestation, as Dan
showed in an artist's conception, that will form a fragmented
distributed microwave dish antenna for communicating with. . .probably
whomever our ancestors were trying to communicate with at Stonehenge. .
.and some less-authorized jokers likewise today try to seek out using
crop circles. Well, you know, they capped the high-energy
physicists before they built the Supercollider, which would've torn up
two countries. But hey, if our ancestors had been ecologically
tidy, we wouldn't today have all those
unnatural historical artifacts, like pyramids and petroglyph graffiti,
that other national parks have been designed around, now would
we? Hmm. . .sorta like using WMDs to find GWB? Yuch!
