I actually do think that someone who already has multiple decades of experience in programming without using AI is probably not producing shoddier code after incorporating it into their workflow

While it’s not impossible that someone like that exists, the number of times I’ve seen someone push LLM generated code that LOOKS okay on a first glance to experienced eyes but turns out to result in things like the code as a whole suddenly ignoring all permission groups and just letting everyone through in one particular area, or allowing directory traversal, or injection, or any number of otherwise rookie mistakes is high enough that everyone, especially programmers with decades of experience should be extremely concerned.
