Definitely true. The only way this is not true is if by some miracle we get an emergent property at a ridiculously large scale, and even then it could be something that could be simplified, which means that scale is at best a way of stumbling upon general intelligence. However, biological brains are incredibly efficient, with very small animal brains demonstrating robust mechanisms of awareness and learning. There are severe cases of brain conditions where the majority of the brain is missing, yet these people can still show awareness and basic emotions. We know gut bacteria affects the brain and how emotions are also linked to the state of our bodies, I think there is a knowledge gap in our understanding of intelligence that involves the necessity for embodiment. Our bodies are potentially doing a big part of the "computations" that make up our ability to have general intelligence. This would also explain a lot of how lower level animals like insects are able to display complex behavior with much simpler brains. AGI might be such a hard problem because it's not just about recreating the "computations" of the brain, but rather the "computations" of an entire organism, where the brain is only doing the coordination and self-awareness.
