Re: “I saw his ass yesterday”
Adding to the potential for increasing bias or lack of flexibility, is the fact that, at street level, particularly with younger speakers who then take the idioms of youth with them as they mature. Language evolves and frequently what may have been rude before becomes an acceptable part of every day speech.
The regular language and even subject matter on TV such as the Graham Norton show for example, would have caused all kinds of trouble back when I lived in the UK.
How does an AI stay updated to the constant evolution of language.
Aside from it not really being intelligent.
