Could AI create a new coding language that was incredibly token efficient to work with?

I asked gpt about this, and it said yes, and gave some good examples of how some python code might look like in a new language, where the language was indeciferable to us, and very short.

This concept must surely have been considered. Would it have any merit?

The concept I imagined, was a language so compact, that it almost resembled instinct, rather than words.
