No, I have noticed that too, but I think that issue is two fold; Just before the AI bullshit started development was already well on its way to being the new welding. I went from regularly working with other people with CS degrees to regularly having to corral super juniors who just finished 6 weeks at a vo-tech summer coding crash course right after high school on the exact same software stack. I think part of the issue is that the code the AIs were trained on was already slipping in quality because they are just the latest salvo in the devaluation of development as a career not the beginning of it.

I can't speak on the rate of buggy software increasing, though it makes sense since the barrier to entry has dropped, however LLMs are now also finding bugs at a much larger scale than ever before.
We're seeing decade old bugs being found, popular software suddenly releasing hundreds of bug fixes at once. It's a double edged sword.
