Be specific, provide examples. Much of the things brains do that we call intelligent are totally unknown to us. We have, quite literally, no idea what algorithms the brain employs. If you want to talk about intelligence, I don’t know why you’re talking about neuron spiking. We don’t talk about semiconductor voltages when we talk about computer programs we’re working on.

AI systems are software, so if you want to build something brain like, you need to understand what the brain is actually like. And we don’t.
