We don't even understand how the brain functions completely, not even close. Until we have a complete understanding of how our own GI works down to the exact bio-mechanical level, we can't achieve AGI.

That's the theoretical basis and path for achieving AGI (if it's even possible). I'm tired of all the "we stick enough data in the magic black box blender and ta-da! AGI!"

Every giant technological break-through throughout history has had a massive underpinning of understanding before ever achieving it. And yet, with the AI bubble somehow we're just about to secretly achieve it, but we can't tell you how.
