I am interested in a well documented case (question and answer precisely) where an AI answer actually solved the problem.
My suspicion: even if artificial intelligence is involved, chatter doesn’t help.
as a side note, the actual problem is most often about :
Concerning “clear” the API “documentation” as provided for users here is rather clear, and not (examples for exceptions?) outdated. The actual püroblem of a programming user, however is often of the kind "What service allows to acces properties and interfaces to do this? Where “this” is a task described the human way, not knowing the terms/names actually used in the core code.
I would never ask AI for working code, but often I had problems of the described kind. An AI language model might actually be able to create such a research tool (much more than an index!), but possibly nobody asked it the right way to do the job.
as a first approximation :
Create a new file (copy file to new file with macro)
this one was a bit less approximative :
this one was not artificial (enough), but still approximatively wrong 
Macro to copy date from cell above gives problem sorting - #10 by fpy
Is one of your examples of the kind?

the above screenshot was just to show the prompt was a simple copy/paste of OP.
these are unfortunately quite frequent. often bugs, limitations, legacy, … from core.
that’s the whole story of Pytoniak, … which is itself not exhaustive.
and it’s not just a problem of terminology.
pin it and read it in the next 2 years
