Should SETI Be Searching for AI Instead of ET?
In the vast expanse of the cosmos, the search for extraterrestrial intelligence (SETI) continues to fascinate and intrigue humanity. However, the question arises: should the focus of such searches shift from extraterrestrial life (ET) to advanced artificial intelligence (AI)? This article explores the differences between these concepts and examines whether the search for AI presents a more promising avenue.
The Nature of Advanced Technology
When discussing species with advanced technology, the terms "artificial intelligence" and "extraterrestrial" may seem similar, yet they encompass profoundly different concepts. While some might argue that searching for ET is futile, given the vastness of the universe, others believe that AI might offer a more viable target. This paradoxical notion—where AI can be seen as both a natural extension of human intelligence and an alien concept—raises intriguing questions about the nature of intelligence and its place in the universe.
The Predominance of Prokaryotic Life
On our own planet, vast numbers of prokaryotic organisms thrive, and it is likely that extraterrestrial life, if it exists, will also be predominantly prokaryotic. Even highly advanced civilizations might have a complex life form that is only detectable through technological signs. For instance, a species capable of crafting bronze would be extraordinarily rare, possibly existing in just a few out of every million galaxies. This rarity underscores the complexity and rarity of intelligent life capable of advanced technology.
Seminal Breakthroughs in Advanced Civilizations
The discovery of a species capable of traversing stars would mark a monumental breakthrough, indicating advanced biological-machine capabilities. Such a species would likely possess sophisticated smart computer software and an extensive database. Despite popular misconceptions, a purely machine-based culture as depicted in sci-fi scenarios is not an accurate representation of what an advanced alien civilization might look like. If an evil AI were to be unleashed, it would not create a new society but would cease to exist unless it was destroyed, leading to no technological or biological survival.
SETI's Scope Beyond Biological Life
It is important to distinguish between the scope of SETI's search. While SETI primarily focuses on finding any form of non-Earth-based intelligence, other groups are dedicated to detecting signs of life or potential life on exoplanets. SETI is not solely searching for biological intelligence; rather, it is looking for any signs of advanced technology and artificial signals.
The Current State of SETI
After 35 years of listening, SETI is still searching for any signals, whether from biological life or AI. While the chances of finding either form of intelligence are significant, some argue that the search for AI might be more promising due to its potential to survive longer and be detectable across vast distances. Despite this, funding remains a critical issue for continued exploration.
As the search continues, it is crucial to maintain a balanced approach, considering both the potential of advanced biological organisms and the likelihood that intelligent signals might originate from highly advanced AI. This exploration can not only expand our understanding of the universe but also inspire new questions and avenues of research in the field of astrobiology.
