@Jyoti Yeah, it's because human brain had a billion years of head start.
Also human brain:
1. Runs on horribly sloooooow hardware. Neurons' latency is like TENS OF MILLISECONDS, that's slower than a 50's computer.
2. But all those neurons are all firing simultaneously. Human brain is infinitely parallelized. And how many threads does a GPU have? Like thousand? That's nothing compared to tens of billions of neurons all running in parallel.
But that's fixable.
