Fuck AI

That's not going to happen in anybody currently alive's lifetime either. The best we can manage right now is the Cedars-Sinai model of a neuron (note the singular!) that approximates the electrical behaviour of a single human neuron. (There are huge biochemical signalling networks in brains that are a large part of brain function as well.)

We are nowhere near close to emulating a single human neuron down to the molecular level, complete with ion channels and all the other raw complexity of the beasts. We've barely begun working out how the biochemistry interacts with and modifies that electrical activity. And this is presupposing that the Orch-OR hypothesis (the one that posits essentially quantum computing in the neuron via microtubules and assorted mechanisms held within those) is wrong. If that's correct, we're even farther behind on emulating a human neuron.

That's A human neuron.

We have about 86 billion or so neurons in the brain.

Oh, and wait! Neurons may not even be the whole picture! It's turning out that we're finding some "thought" happening outside of the neurons in the brain.

Did I mention that this is all the static structures of the brain? As little as we know about those, we know even less about the dynamic interaction of things. Biochemical weighting. Plasticity vs. rigidity. Dendrite pruning and regrowth. We know none of this yet, except that they exist.

Oopsie!
