The AI model is likely trained on Stack Overflow posts, or otherwise related content from wherever off the internet, so most likely it will have ripped off enough hand-written posts or articles on how to quit Vim. So of course it can regurgitate the required keystrokes on command.

And will the writers of those posts, who contributed their knowledge to help out their fellow humans, get a fraction of a penny for the hundreds and thousands and millions of dollars of profit the AI corps are making off the backs of their labour? I somehow doubt it.
