Yup. I think this is the best point of comparison - a 4-6 year old kid. Specifically, one that hasn't gone to school yet. The difference between a typical 6-year old and a typical adult is in big part that the latter spent 10+ years being systematically fine-tuned.
Logic, arithmetics, algebra, precisely following steps of an algorithm - those are not skills one "kinda" just "gets" at some point, they're trained by deliberate practice, by solving lots and lots of problems specifically constructed to exercise those skills.
Point being, get GPT-4 through school, and then compare with adult performance on math-adjacent tasks. Or at least give it a chance by prompting it to solve it step-by-step as a problem, so it can search closer to the slice of latent space that encodes for relevant examples of similar problems and methods of solving them.
I started seriously using computers at 2.5, and I started writing and recording songs with a tape recorder at 3, won a local award for one song, and playing chess at 4. I know plenty of people with similar experiences. If you nurture kids and don't treat them like they're stupid, they can do some quite impressive things.
Anecdote: admittedly, I'm autistic as are the people I know, so maybe that's not a good sample. I struggle with a lot of basic shit even as an adult. Oh god, I empathize with the hypothetical GPT5.
