Search for Extraterrestrial Intelligence
Is this the intelligent thing to do?
I suspect that there are at least two types of ETI, Extra Terrestrial Intelligence. Those that we are searching for now must have a high technological civilizations. I believe or I should say I am guessing that there are a few high technological civilizations in our universe. I am confident that there are many more ETI without any electronic sophistication. How high can a civilization advance without electronic technology? During the years of high tech SETI we will find none or very few intelligent and technological advanced life or Techies in the universe. From our vantage point we will only be able to discover Techies.
As the noted astronomer, Carl Sagan once remarked, that if the Greek spirit had continued unencumbered we would not be dreaming about traveling to the stars but would have returned long ago and now we would be launching fleets of ships for missions of exploration, trade and immigration. If Sagan was right the discovery of civilizations with non-electronic technology may have been discovered by these interstellar missions by now. This may have translated to a more peaceful earth and an understanding of our place in the universe.
There are primitive societies, PICE and Thales civilizations. Civilizations reaching the Thales level lead to technology as it did on our planet. The Thales civilizations however can lead to and I am not even going to guess here but to great advances unforeseen by us.
The pre-Thales state includes the civilizations of Persia, India, China and Egypt (and others) or PICE. There are many pre-Thales or PICE civilizations in the Universe. We will discover many civilizations in the PICE state. On earth the Thales state lasted for only several thousand years. In the great expanse of the universe we will find many civilizations stuck in the PICE state for tens of thousands. Some of these PICE civilizations may last even over100,000 years but eventfully fade away as their resources are exhausted. The PICE civilizations then revert to a more primitive state and may never recover to a high state again. Thales is the first scientist on this planet. From the time of Thales to technological society is relatively short.
I predict that planets with pre-PICE those with primitive societies will be
Lower life forms will be extremely abundant.
A few PICE civilizations get to the
Thales or Greek state which lead to science and from there to technology but can
lead to other states of advanced societies. There is always the threat of the
Some planet must be first to to reach a high technological state. Could we, the humans of Earth be the first such planet in the Universe? I suspect that the answer is "no" as the realm is not only space and the amount of available planets able to produce high civilizations but the the great span of time. In the great span of 12 billion years someone else must surely have been first.
