This article is very interesting because it talks about the Singularity, which is the point in the future when robots and artificial intelligence will surpass the combined intelligence of all humans on earth. The article makes an interesting point that because the speed of the processor that costs $1000 is increasing exponentially, until 2045 which is when the processing speed of all silicon will exceed human intelligence. At this point, speculators say, that humans may merge with their robot counterparts and potentially become immortal and ridiculously intelligent. or, the robots will go Terminator on the human race and try to wipe us out because they see us as a threat to the continuation of the earth's ecosystem.
Either way, the Singularity is becoming less of a theory and more of an inevitable reality.
