Why is it that they have to war? Why is it they have to have economies? Why is it they have to do anything we do here?
It never made sense to me.
And it’s a thick fog of organic molecules that dissolves entire planets on contact.
I do get a little laugh out of the “the aliens will deem us unworthy” stuff. Christianity called, it wants its mythology back!
I think you'll find the speed of thought is much lower than the speed of light, I believe nerve impulses max out at about 120 m/s. The difficulty of supporting such a large mass of nerve tissue is also a problem. There is also the trouble of whether intelligence is purely electrically mediated or if it relies on the soup of hormones and molecular machinery of DNA and proteins for some of its functions. We also need to specifically consider the neocortex here since it is the only differentiating brain structure in animals with human intelligence. Other animals have much larger brains but no signs of human like abilities.
If you are suggesting we build an artificial brain then we need to wait at least a few more years if not decades to find out if that is possible. The current transformer models are quite advanced at language production and seem to have some simple reasoning abilities but they are very far from being intelligent.
