ChatGPT's attempt:
https://gist.github.com/iameli/d9a5b715ec9baa5b11063888e054d...Are those two responses enough to say it's invented a language? Probably not. But it's already farther along than I would have gotten if you asked me to do such a thing.
If I kept prompting it for hours, I bet it would start to contradict itself and lose track of the rules it had already established, but so would I. If I were actually inventing a language, I'd take months and keep extensive cross-referenced documentation on grammar and syntax and vocabulary. We don't _let_ ChatGPT do that, it has no mechanism for persisting its ideas like that. But like... neither would I if you took away my notebook and the parts of my brain that persist long-term memory.
I guess my interpretation here - I see differences in _capabilities_, but not differences in actual _intelligence_.
