Does someone who is blind is not conscious then? How about when someone who is paralysed? or deaf? or someone with low IQ or mental illness?
Stephen Hawking was paralysed most of his life but was a smart guy. If he was not only paralysed but also blind and deaf he would be smart guy still.
I don't think AGI needs to have a body, sensorimotor interaction or even vision to be conscious. We need those for training - if you would be blind, paralysed, deaf from the beginning it would be hard for you learn anything and interact in any way.
Machines have 6th sense that humans don't have - kind of a telepathy where they can exchange tokens/thoughts with different machines or humans much faster than we humans can type or speak.
