We know for a fact that human level general intelligence can be achieved on a relatively modest power budget. A human brain runs on somewhere from about 20-100W, depending on how much of the rest of the body's metabolism you attribute to supporting it.
The fact that the human brain, heck all brains, are so much more efficient than “state of the art” nnets, in terms of architecture, power consumption, training cost, what have you … while also being way more versatile and robust … is what convinces me that this is not the path that leads to AGI.
