Background

The role of hard-wired language in AI

Since the 1960s Noam Chomsky states with Universal Grammar (UG) theory that certain parts of human language appear to be hard-wired. In 2014 Max Planck researcher demonstrated that “Huh” can be considered as such a natural law in spoken communication. This proof later won the IG Nobel Prize for Alternative Science.
