Actual AI would be more than “just math”, but LLMs aren’t AI, so the comparison is moot.

Now we’ve built a collection of simulated neurons, at a scale close to that of the human brain, and trained it on the entirety of the human language

We are not even close to anything of the sort. We’ve got a probability machine that’s mostly decent at human language. The other two are much farther down the road (if they’re even possible) than you or the rest of the tech bros are trying to convince everyone else of.
