Depends on how you use the word. I use and understand the term ‘vibecoding’ in a similar way the author of the article you link to does: instructing AI to write code for you. That’s how I normally see the word used and how some English dictionaries define it. [1] [2] [3] By those definitions, Raku++ is vibecoded.

Wikitionary adds the nuance of the prompter not understanding the generated code well. [4] If we go by that definition, Raku++ is not vibecoded. Would you say this definition is more correct? (I only go by what I’ve been hearing and able to find so far, so I might have missed something.)
