nodes and weights are different from neurons and connections. Neurons are also not the only components in the brain which contribute to intelligence.

google recently scanned a 1mm cube of human brain which was 1.5Petabytes of raw data. The AI hardware that Google trains on is multiple racks.

I think a better analogy would be between an entire google datacenter (including all the networking, storage, sensors, processors, and memory) and a human body although even then it's a stretch.
