In search of extraterrestrial intelligence, we often look for signs
of intelligence, technology and communications, similar to our own. But,
as astronomer Jill Tarter observes, such an approach means searching
for detectable technosignatures, such as radio transmissions, rather
than intelligence. Now scientists are thinking about whether artificial
intelligence can help us in the search for alien intellect.
“Deciphering” the intellect
Reflecting on the extraterrestrial mind, it is useful to remember
that people are not the only intelligent life on Earth. Chimpanzees have
culture and tools, spiders process information with cobwebs, cetaceans
communicate in dialects, crows understand analogies, and beavers are
fine engineers. Intellect (not human), language, culture and technology –
all this is around us.
The alien mind can be like an octopus, an ant, a dolphin or a car – or it will radically differ from everything on the Earth.
We often imagine extraterrestrial life in relation to our ideas about
differences, but these ideas are not universal even on Earth and are
unlikely to be universal in interstellar space. And if some of us have
only recently realized that there is a reason on the earth besides
human, what do we miss, presenting extraterrestrial life?
In early 2018, astronomers, neuroscientists, anthropologists, AI
researchers, historians, and others gathered at the seminar “Deciphering
Alien Intelligence” at the SETI Institute in the Silicon Valley.
Astrobiologist Natalie Kabrol organized this seminar as part of her work
of 2016, “Thinking aliens”, in which she called on SETI to compile a
new roadmap and presented a long-term vision of “finding a life we do
not know”.
In his article, Kabrol asks how SETI can move away from “searching
for other versions of itself” and thinking “beyond its own brains” to
imagine a completely different extraterrestrial intelligence.
Think differently
The Silicon Valley is famous for being contrary to the generally
accepted opinion, and this culture overlaps with SETI’s research. Since
the US government stopped financing SETI in the mid-1990s, ideas,
technology and financing from the Silicon Valley are becoming
increasingly important.
For example, the Allen telescope array at the SETI Institute is named
in honor of Microsoft co-founder Paul Allen, who has invested more than
$ 25 million in the project. In 2015, investor Yuri Milner announced
Breakthrough Listen, a ten-year initiative to search for
extraterrestrial life.
Now the SETI Institute, NASA, Intel, IBM and other partners are
trying to solve the problems of space science with the help of
artificial intelligence and the development of a program called Frontier
Development Lab.
Lucianne Valkovich, chairman of the Library of Congress from
astrobiologists, describes one of the methods based on AI as an
“agnostic search for signals”. This means using machine learning
techniques to search for any data set without predefined categories,
which allows you to decompose data according to their “natural
categories”. The software then gives us an idea of the basis for the
separation, and what data might be of interest for further study.
It turned out that SETI researchers believe that artificial
intelligence will help in their work, because machine learning is good
at detecting differences. However, its success depends on how we
designate the very idea, the very concept of “difference”.
Smarter than mucus
Smarter than mucus
Thinking beyond our brain also means thinking beyond our scientific, social and cultural systems. How to achieve this?
AI was used to find analogues of possible broadcasts of aliens, but
now scientists plan to use it to search for things that we have not yet
looked for.
Graham McIntosh, an AI consultant at the seminar of the SETI
Institute, said that aliens can do things that we can not imagine, use
technologies that we did not even think of. AI, in his opinion, could
think for us in this direction.
Maybe we can not get smarter, suggests Mackintosh, but we can make
machines that are smarter than us. The astrophysicist Martin Ric
expressed the similar hope that AI can lead to “an intellect that
surpasses people in the same way as we intellectually surpass mucus.”
First contact
If we had met with extraterrestrial mucus, what could we have assumed
about her intelligence? One of the problems with the search for
extraterrestrial intelligence is that we do not know the boundaries of
life or intelligence, so we must be open to all possible differences.
We could find the mind in forms that our science historically
ignored: microbial colonies, insects or other complex systems, such as
symbiotic connections between plants and fungi in mycorrhizal networks.
Intellect can manifest itself in the atmosphere or geology on a
planetary scale or in astrophysical phenomena. What seems to be a
background process in the universe or a part of nature may prove to be
reasonable.
The largest living object on Earth can be the fungus Armilaria
ostoyae in the Blue Mountains of Eastern Oregon: it extends for 10
square kilometers and it is from 2 to 9 thousand years old.
Although mushrooms are not usually associated with intelligence, they
remind us that one should expect everyone to search for life and mind
in the universe and that life can be right under our feet, in the form
of the same fungus or microbes.
And if you think that the intellect can represent anything, then the
first contact can confront us with anything: whether it’s a common
artificial intelligence, reasonable machines or something else. Perhaps
an artificial intellect, free from human prejudices, even to some
extent, can help us.
