We do on the other hand know for a fact it's possible to run an instance of consciousness in a volume of about a liter that consumes like 20 watts (aka your average human brain), so there's something probably wrong with our general approach to the matter. GPT-3 already uses about twice as many parameters as our organic counterparts do, with much worse results. And it even doesn't have to process a ridiculously large stream of sensor data and run an entire body of muscle actuators at the same time.
