I understand his point is not that we have enough CPU and RAM to simulate a human brain. We do not. His point seems to be that the observable memory capacity of the human brain is on the order of TB to PB. He doesn’t go too deep into the compute part but the analogy with self-driving cars seems suitable. After all quite a big part of the brain is devoted to image processing and object detection. I think it is not inconceivable that there are better algorithms than what the brain has to make do with for the intelligence part.
He’s specifically talking about building a computer not any more efficient than a brain algorithm wise and saying we have enough compute to do this.
He is incorrect because he is not factoring in the compute architecture. The reason you should consider my judgement is I am a working computer engineer and I have personally designed systems (for smaller scale tasks, I am not the architect for the self driving team I work for now)
Of course more efficient algorithms exist but by definition they take time and effort to find. And we do not know how much more efficient a system we can build and still have sentience.
