Even if the jury is still out, I would still say you are both right already.
The amount of slop produced even in company setting is staggering and I don't like it one bit that neither the submitter nor the reviewer of the PR paid due dilligence. And I am only complaining because it then becomes my problem. So, then I have to start nagging people to clean that up. I can say with 100% certainty that the problems I face now would not have happened without LLMs.
That said, used with care, with proper supervision, with dilligence to review what LLMs did, I still think they can be and are beneficial.
I think that we are just not used to getting results of questionable quality from the tools we use. So, I am hopeful that we will learn and it will improve with time but still find myself dreading the age of the vibe coder.
