I don't think any of the "frontal lobe" techs fit. They're all just language or learning models without any actual memory, reasoning or problem solving abilities.

In fact what's missing overall is just that - logic, calculations, bookkeeping, etc. And that's not really you even need AI for; we've had, say, WolframAlpha for years now and it's absolutely amazing. "All you need" is an AI that can interface with services like it for that part. But we don't really have that as far as I know.
