Are tools like ChatGPT killing the cover letters?

I write what I consider to be awesome cover letters, if simply because recruiters tend to mention something from them when they reply. What I wrote was clearly read in full.

ChatGPT produces this bland and generic resume summary. I wish it could generate something I thought awesome, but it cannot.

I would note that my teachers would be appalled at how casual and filled with puns and jokes they are, so it is not by any means the "Dear Hiring Manager" kind of cover letter.

Or is the worthlessness of cover letters killing cover letters?
