A computer program can be taught to recognize patterns and compare to them know variables, and from there determine whether something is an enemy threat or not. Where the flaw in that system is and where the human element is not only vital but critical, is that human can not only recognize and compare patterns for possible threat, they can sift through that information and recognize when something merely has the appearance of a threat. Human, unlike computers, can sort out civilian building and natural formations from true enemy installations. Therefore saving civilian and military lives.
Russia, cuba love to play soccer. Sports are not linked to any economic system. Cuba is an exemple that a nation can be communist and play soccer which are popular in capitalist nation. I think we have to rely on human intelligence today and trying to live together beyond how large our differences can be.
In recent years, we as a country have ignored information received by ambassadors and operatives, who are stationed in various parts of the world. An example of this would be Benghazi, Libya. The deaths of the US embassy members could have been prevented, simply by taking the operatives word that there would be an attack on our embassy, instead of disregarding the information.
I assume that when we refer to machines and humans "co-evolving" their intelligence, we're saying that their intelligence growth is trending together over time. That is to say that no one entity "pulls away" and becomes vastly smarter than the other.
Research talks a lot about an "intelligence explosion." This explosion would occur after super intelligent beings are created, as they will be able to improve upon their own intelligence with a superior skill-set. And the next generation with its superior skill-set. And on and on. The effect would very likely be exponential. For computers, this would be a machine modifying its own hardware and software to make improvements to itself.
