Even if it doesn’t work the same way, humans anthropomorphing pattern detection will grapple on to it as “same function, so same thing”. As we slowly build general AI, other “things that don’t work that way” will be attached on to it until we have a full general AI whose brain works nothing like humans but has pieces that work in similar fashions.
Sort of like how 60 Watt LED light bulbs don’t use 60 Watts. “They produce the same about of light, so they must use the same amount of energy!”
