<human>:  How feasible do you think it is to emulate the human brain?
<bot>: Brain emulation is very difficult. It is not clear that it is possible. In order to emulate a brain, we need to understand how the brain works. We do not currently have a good understanding of how the brain works. Even if we did, we would need to build a very large computer to run the simulation. The problem is that the computer would need to have trillions of neurons, which is impossible.
