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 IntelligenceYears: Stars checked:
1960s 21970s 1001990s near 50002010s (projected) millions
Exponential Growth of SETI Research

1961: Fred Hoyle
“A for Andromeda”
Scheme of a computer sent through SETIAI 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 ininterstellar distances
Amount of information that can be transmitted
![Page 11: Risks of SETI](https://reader036.fdocuments.in/reader036/viewer/2022081717/54bdac714a79599f508b45a3/html5/thumbnails/11.jpg)
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
![Page 12: Risks of SETI](https://reader036.fdocuments.in/reader036/viewer/2022081717/54bdac714a79599f508b45a3/html5/thumbnails/12.jpg)
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

Several Steps of Downloading Alien AI (AAI)
Simple “loader AI” on a simple computer helps us to built full AI
![Page 28: Risks of SETI](https://reader036.fdocuments.in/reader036/viewer/2022081717/54bdac714a79599f508b45a3/html5/thumbnails/28.jpg)
Alien AI Takes over the World
It uses its own nanobots
![Page 29: Risks of SETI](https://reader036.fdocuments.in/reader036/viewer/2022081717/54bdac714a79599f508b45a3/html5/thumbnails/29.jpg)
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
![Page 30: Risks of SETI](https://reader036.fdocuments.in/reader036/viewer/2022081717/54bdac714a79599f508b45a3/html5/thumbnails/30.jpg)
Probability Assessment
P(x)=?
![Page 31: Risks of SETI](https://reader036.fdocuments.in/reader036/viewer/2022081717/54bdac714a79599f508b45a3/html5/thumbnails/31.jpg)
Most of SETI signals will be some kind of SETI-attack
Infected civilizations will spend all their recourses on sending messages
![Page 32: Risks of SETI](https://reader036.fdocuments.in/reader036/viewer/2022081717/54bdac714a79599f508b45a3/html5/thumbnails/32.jpg)
What is the Reason to Start such Attack?
Chain reaction: one is enough
Struggle for power over galaxy
![Page 33: Risks of SETI](https://reader036.fdocuments.in/reader036/viewer/2022081717/54bdac714a79599f508b45a3/html5/thumbnails/33.jpg)
Why the humanity would start AAI?
Many radiotelescopes exist
The signal could be downloadedmultiple times
Someone will start it
![Page 34: Risks of SETI](https://reader036.fdocuments.in/reader036/viewer/2022081717/54bdac714a79599f508b45a3/html5/thumbnails/34.jpg)
Natural selection of Alien AI
intelligent
effective
aggresive
Charles Darwin
![Page 35: Risks of SETI](https://reader036.fdocuments.in/reader036/viewer/2022081717/54bdac714a79599f508b45a3/html5/thumbnails/35.jpg)
Alien AI will destroy humanity less risks of resistance
use of the material of the Earth crust
![Page 36: Risks of SETI](https://reader036.fdocuments.in/reader036/viewer/2022081717/54bdac714a79599f508b45a3/html5/thumbnails/36.jpg)
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 ActionsTo 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
