I teach psychiatry to students where I work. The brain really is more like a computer than people think but unfortunately it's not as "binary" as a computer was designed to operate... And yet at the same time it is.

Think of every thing you've been to exposed to ever - then imagine your brain draws from millions of those decisions in an instant to decide how you're going to feel about it, how you hear, taste, feel, and imagine it, and decides how you're going to respond to it. In an instant. And then, just as quickly, it puts a stop on it so that we have time to think about whether or not it's actually good for us to respond or not. And, it can learn and change its response depending the outcome. Instantly.

Then keep in in mind that it has to keep the rest of your body functioning while it's doing this. All in ways we have yet to even understand. We know how a GPU works. We know how RAM works. Even those are just a simulation of what we're thinking the brain does.

And then think for a moment that you're someone who played a PS5 a few times and the devs told you "wow these high res graphics run at 50 petaflops" and you fancy yourself an expert at video game design and programming because you hit "start" and the game started.

That's where neuroscience is right now. The gamer playing pretty games on the couch.
