Just to test out the OP articles theory, I was about to write some unit tests. I decided to let Opus 4.5 have a go. It did a pretty good job, but I spent probably as much time parsing what it had done as I would have writing the code from scratch. I still needed to clean it up, and of course, unsurprisingly, it had made a few tests that only really exercised the mocking it had made. A kind of mistake I wouldn't be caught dead sending in for peer review.
I'm glad the OP feels fine just letting Opus do whatever it wants without a pause to look under the covers, and perhaps we all have to learn to stop worrying and love the LLM? But I think really, here and now, we're witness to just another hype article written by a professional blogger and speaker, who's highly motivated to write engagement bait like this.
