A child may not be able to count, because they don't yet understand the concept, but may be able to reason at a more basic level, yes. But GPT has ingested most of the books in the world and the entire internet. So if it hasn't learned to count, or what counting is by now, what is going to change? A child can learn the concept, GPT cannot. It doesn't understand concepts at all, it only seems like it does because the output is so close to what beings that do understand concepts generate themselves, and it's mimicking that.
