there was a paper a bit ago that showed that to trigger a single neuron with 99% accuracy you need an 8 layer deep neural network, that is for a SINGLE neuron, yeah not happening, brains are too complex for us to have sentient AI right now.,(reply>), @Magnulus76 no it isn't, far from it.,(reply>), GPT-3's neural network is much more comparable to a human brain in terms of complexity.,(reply>), @Imjashingyou there are like a dozen creatures without brains at all. Just because it is common where we are, doesn't mean it is the standard. We just think its a safe bet because of what we experience. Hence the search for life is usually carbon based even though its possible some life may be not,(reply>), @TurboGamingUK considering all major life has a brain as we know it, or some form of controlling organ that doesn't have high functions.  I would say there is a lot of evidence to say it's extremely likely that it would need to be a brain like structure to do more then it can already do like regulate a simple machine.,(reply>), @Chickenmonger I wasn't talking stuff we don't understand fully. I was talking about an old treatment for epilepsy that involves separation of the brain hemispheres. Each side is a separate entity so that parts of the body controlled by the left brain can disagree with the right brain. The left side is a silent trapped component in our brains normally. After separation it has to communicate non verbally since it has no access to the mouth but it is clearly it's own consciousness.
