> Human brains aren’t limited to the standard human body plan.But as the body starts to lose function (i.e. disability), we start to consider those humans special intelligences instead of general intelligences. The body and mind are intrinsically linked.
Best we can tell the human brain is bootstrapped to work with the human body with specialized functions, notably functions to keep it alive. It can go beyond those predefined behaviours, but not beyond its own self. If you placed the brain in an entirely different body, that which it doesn't recognize, it would quickly die.
As that pertains to artificial analogs, that means you can't just throw AGI at your hardware and see it function. You still need to manually prepare the bulk of the foundational software, contrary to the promise you envision. The generality of AGI is limited to how general its hardware is. If the hardware is specialized, the intelligence will be beholden to being specialized as well.
There is a hypothetical world where you can throw intelligence at any random hardware and watch it go, realizing the promise, but we call that ASI.
