“The natural progression of evolution is from biological to cyborg. Once biological life gets smart enough, it builds cyborgs who are so superior to them, the cyborgs take over and dispense with the biological life.”
I recently read an article about that very subject. The article posited that by 2050 we’ll have humanoid robots that are so lifelike and physically able, you won’t be able to tell them apart from biological humans.
In addition, the author postulates that they’ll run on artificial intelligence that, by that time, will be more advanced than human intelligence.
He went on to plead with lawmakers and robotics manufacturers to build in aoutomatic controls, to prevent this new race of cyborgs/androids from destroying humankind.
These advances are coming, and we’re going to have to deal with the consequences.
That has also been a sci-fi theme for years (Battlestar Galactica, SkyNet).
The first scientist I saw to suggest it was Richard Dawkins in his book "The Blind Watchmaker" (1986, revised 1996). He brought it up in the context of, why do we see no intermediate life form that used something simpler than DNA and RNA? Those are very complex molecules, and they couldn't have sprung up from nothing.
So he suggested, maybe whatever came before just got out-competed for survival by the far more advanced DNA life forms, and he drew the analogy to cyborgs taking over from their human predecessors and wiping out all traces of the humans.
