The paper title is clickbait and therefore the HN comments are focused on various low-effort reactionary noise, but it seems like an interesting study.
I would not be surprised to find StackOverflow usage dropped significantly because of ChatGPT. It's simply a much more effective tool for getting help with typical programming problems. Not as good of a resource for expert-level or architectural advice, but that's okay with me. Basic "debugging via internet" is much easier to do with an interactive service with lots of knowledge.
It's often pretty helpful just pasting an entire error message with backtrace into ChatGPT and seeing what it thinks.
If you're only pasting backtraces, you're not taking advantage of its coding ability. You can describe the problem, have it write some code, then iterate by telling it what to add, cases you want it to handle, add features to the code. It's been doing a pretty good job of helping me designing a database down to the actual CREATE TABLE statements for me as well.
