As for your question, I don't know about the person you're replying to, but for me any software where part of the source was provided by a LLM is a no-go.
They're credible text generators, without any understanding of, well, anything really. Using them to generate source code, and then using it, is sheer insanity.
One might suggest it means I soon won't be able to use any software; fortunately the entire fever dream that is the ongoing "AI" bubble will soon stop, so I'm hoping that won't be the case.
As for it being a bubble that will stop completely, that ship has long since sailed and I assume you're inadvertently using LLM generated code somewhere in your software stack already, due to news reports saying certain companies are already using LLMs in their codebase.
Indeed, we'll see.
Maybe it's a scene from a show I've seen already??
