Despite of interstellar travel stories in science fiction let a person feel very childish, but Darwin pointed out that organisms cannot be survived in the interstellar travel, after all the long trek across generations, even if the vehicle running at the speed of light, also need to tens of thousands of years across the Milky Way disk of stars, at the same time, through the Milky Way halo structure of 10 times longer. So if we meet an alien, is likely to be their science and technology products, technology product debris may over several billion years accumulation in interstellar space, like a plastic bottle accumulation on the surface, the opportunity to detect an alien technology remains can be simply calculated from us in a nearby unit volume Numbers, rather than from the drake equation, Strictly speaking, this formula applies only to the communication signals of existing civilizations.
Do alien intelligences follow the "fundamental theory of moral metaphysics" proposed by German philosopher Immanuel Kant? This will be the main concern of future human contact with aliens. Based on the history of human development, we doubt whether moral ethics will be accepted by all intelligent beings in the galaxy. That is to say, it is difficult to determine whether the aliens we will encounter in the future will be friends or enemies.
Conversely, a code of conduct that would allow alien technological systems to dominate the galaxy would also make them more likely to be our first contact with aliens. In effect, such a code of conduct would serve as a Darwinian evolution by natural selection, favoring systems that persist over the long term, reproduce and spread as quickly as possible, and mitigate damage from interstellar travel by self-healing mechanisms. So far, this code of conduct probably applies to the habitable zone around all stars in the Milky Way, including the solar system. Most of the stars in our galaxy are billions of years older than our sun, which means that these stars are home to advanced technologies that are more advanced than our own and likely once ruled the Galaxy as a species of intelligent technology.
In the next decade, human's artificial intelligence system is likely to replace human intelligence, so we have reasons to think that artificial intelligence system, which is connected with a 3 d printer can reproduce themselves in other planet, and machine learning to adapt to the changing environment of interplanetary, can hibernate, in the long trek in the area of nearby stars start charging power supply, use of a star's light energy. With that in mind, it's safe to assume that the mysterious interstellar object 'Oumuamua's flat, thin structure collects sunlight to recharge its batteries. At the same time, flat structures are suitable as receivers for communications from probes placed on habitable planets, such as Earth or Mars.
Talk about this kind of detector, if the pentagon report submitted to congress to discuss one or more of the unknown aerial phenomena (UAP) derived from another planet, then scientists will need to collect more data to interpret the behavior of potential alien life purpose, because any signal from the starting point of their time delay, And since it's likely to be an AI system operating in autonomous flight mode, how can we tell if an autonomous alien AI system is friend or foe?
Conventional wisdom about aliens may have been misleading, as was the story of the Greeks using the Trojan Horse to sneak into Troy and win the war. Therefore, we should first study the behavior patterns of alien probes to figure out what types of objects and data they are looking for. Second, we should examine and analyze how potential extraterrestrial life responds to our actions, and when there is no alternative, we should engage their attention in ways that promote our self-interest.
Most importantly, humans should avoid sending mixed messages to these probes, because doing so would confuse our understanding of potential alien reactions, and any decisions on how to act must be coordinated by international organizations like the United Nations, with ongoing oversight by government agencies in every country on Earth.
Ultimately we may need to use our own AI systems to properly explain alien AI systems, an experience like proving that our children are better at computers than we are, a technological game in which expertise and artificial intelligence levels may be more important than physical and natural intelligence.
As the most intelligent species on earth, we have always been in control of our own destiny, and that assumption may not be true if we encounter alien AI systems in the future, so technological sophistication brings a sense of urgency to Darwinian survival in the race of galactic civilizations. Only if the science and technology are sufficiently advanced can we overcome the threat from alien technological devices. Hopefully, among the galactic races, the artificial intelligence systems of earth humans will outsmart the alien intelligence, and like a gunfight in the Wild West, the survivors may be the first to pull a gun without hesitation.
