We understand what "smart" means in relation to what one can do in the world, but that says nothing of what it actually is. It's like if I make an analogy: "That guy is like a dog chasing a bone." It only means something if you understand it, it has no substance on its own. I feel the same way about the way people use terms like "smart," "intelligent" they only mean something if we already know what they mean, but we only know what they mean in relation to the world, not their character independent of it. I do see the trajectories being different, but I believe they must also converge at some point. Edit: Also, the documentary "Baby Geniuses" has extensive evidence that babies are really smart, they just can't communicate how smart they are.
