Maybe it's just me but if I felt like my application's error messages weren't easy enough to understand I'd try to improve the messages instead of throwing all the context at an AI and hoping for the best.
But it can help us humans understand them better.
Both can and are coexisting just fine.
I have read and re-read this article and I don’t understand how this is better for any purpose other than “we put AI in something, increase our stock price!”
Isn’t that just what we humans do with our educated guesses?
The link could even be parameterized so the URLs or other elements related to the error replace placeholders in the doc. But I'm sure a developer is capable of enough abstraction to replace example data themselves.
