Give
Ray Kurzweil an early “eureka” moment while developing one of his many accessibility inventions so that he starts successfully working on cybernetics. If his eureka is linked to a brain-machine interface, this can potentially be leveraged to make more robust, human-like AI’s (as the interface makes the brain easier to study) in the future. I’d say put it in the mid-80’s, which should give enough time for GitS/Armitage III (or
Deus Ex: Human Revolution, even if nobody asked for it) shenanigans by the current day.
