Risks of SETI

Passive SETI is a much more dangerous 	
			 activity than messaging to stars
Two Main Premises
Existence of
ET civilizations
The possiblity of AI
Search for Extra-Terrestrial Intelligence
Years: Stars checked:
1960s 2
1970s 100
1990s near 5000
2010s (projected) millions
Exponential Growth of SETI Research
1961: Fred Hoyle
“A for Andromeda”
Scheme of a computer sent through SETI
AI
It tries to take over the world
“Mind Children”,
chapter “A Caveat for SETI”
“Virus behavior” of SETI-attack
It spreads like infection in the Universe
1988: Hans Moravec
“Do potential SETI signals need to be decon-
taminated?”, Acta Astronautica
First scientific article about SETI-attack
SETI-attack message could have a
trick
		 2004: Richard Carrigan
Expressed conserns about risks
of contacts with aliens
2010: Stephen Hawking
Current technologies
allow to send gigabytes in
interstellar distances
Amount of information
that can be transmitted
Human genome is less then
1 gigabyte
Conscious memory is
2.5 gigabytes
Seed AI could have the same
size and could be sent in
interstellar distances
		 Size of the Seed AI
Seed AI can evolve extremely
quickly
It could easily outsmart humans
and take over the world
Risks of AI are underestimated
It is impossible to keep AI in the
“black box”
It is impossible to recognize
dangerous intentions of an AI in
advance
E. Yudkowsky
Possible Scenario of SETI-attack
ET Create a Beacon in Space
Wikipedia/Nasa
Something like strange star to attract attention
Information-transmitting
Radio Station near the Beacon
Information Consists of 0 and 1
00111100011110001111000
111000111111111111111111
000111111000000111111111
00001110001101111100001
0 and 1 Allow to Send Images
Images Allow to Send Messages
						 and Schemes
Arecibo message,
1974,
Puerto-Rico.
23 x 73 bits.
Contains main information
about the Earth, DNA and the
humans.
The “Pioneer”
Spacecraft
message,
1972
The “Voyager”
spacecraft
message
teaching math
Copernican Mediocrity Principle:
				 The Earth is Typical
		 We shall understand alliens
The Possible Trick
	 “If you make our device we promise”:
Galactic Internet
Immortality
Power over enemies
etc
Three Parts of the Message
The bait or trick
The scheme of a computer
The large program to it
ET can Send to Us a Scheme of a
					 Simple Computer
Turing-
machine
made from
Lego
Principle electric cheme
of a simple
AND-NOT
logical element
ZX spectrum
8-bit computer
Several Steps of Downloading
						 Alien AI (AAI)
Simple “loader AI” on a simple
computer helps us to built full AI
Alien AI Takes over the World
				 It uses its own nanobots
Alien AI creates new lighthouse
and starts to transmit itself to 		
						 the Universe
Dyson sphere
as a new
beacon
It uses all the material of the Solar
system to build large transmitters
Probability Assessment
P(x)=?
Most of SETI signals will be
some kind of SETI-attack
Infected civilizations will spend all
their recourses on sending
messages
What is the Reason to
					 Start such Attack?
Chain reaction:
one is enough
Struggle for power
over galaxy
Why the humanity would start AAI?
Many
radiotelescopes
exist
The signal could be
downloaded
multiple times
Someone will start it
Natural selection of Alien AI
intelligent
effective
aggresive
Charles Darwin
Alien AI will destroy humanity
		 less risks of resistance
		 use of the material of the Earth crust
My Estimation of Probability
		 ET exist: 1 %
		 AI as program is possible: 90%
		 SETI-attacks are typical: 50%
		 SETI-attack will reach success: 50 %
		 SETI-attack lead to the human extinction: 50 %
		 Extinction probability from the
	 	SETI-attack: 0.12 %
Necessary Actions
To rise awareness about the problem
To change the guidelines for the SETI research
To consider the prohibition of SETI before we get our
own AI
