Generative grammar is extremely nativist. The truth is, people will learn anything society forces them to learn. In Piraha society nobody is forced to learn recursion and consequently nobody thinks recursively or in numbers.

The global languages of A.D. 2023 (English, French, etc...) are probably stuck in a similar "Chomsky tarpit" as Piraha, but because we're so globalized and together nobody is brave enough to look out of this tarpit.

I am constructing a conlang codename LXX (because it has 70 phonemes, 15 vowels and 55 consonants, but they were carefully chosen to be learnable to pronounce unlike Ithkuil) for the purpose of getting at least one human society out of this tarpit.
