When talking about Stelarc’s Third Hand device it reminded me about this really interesting video I had seen. For those who don’t know, the third arm piece was attached to his forearm and controlled through abdominal and leg muscle movements. Using this third arm he wrote down evolution of a clear board, as seen here:
This, to me, is a way of saying the next step in evolution is cyborg technologies. This is somewhat true I’d say, or at least it has some merit, but to me it reminded me of something else. I saw this video by a youtuber named CGP Grey, he makes in depth videos explain small topic that range heavily. This video talks about people who have had their corpus callosum cut. They find that these people can have disagreement with their own two hemispheres of the brain. The right hand might want something, but the left hand might want something else, because the two hemisphere can communicate internally, they do externally. This split also allows the people to do something like draw two different pictures at once with either hand.
So this third hand that seems really hard to control is pretty similar to how our mind already work, which I find interesting.
