Reposting a question for Ed Zitron, I'll forward responses. He asked on Bluesky and will get sub-Mastodon-tier answers:

"This is a serious question and I would be delighted if I only hear great things but, software engineers: both before and after LLMs, how often in your professional lives have you run into software engineers that seem completely useless or lacking in basic knowledge? I hope the answer is rarely"

@ludicity Sadly, the answer is not “rarely”. In the past few years, I’ve been fortunate enough to work in a fairly stable group, so can’t really differentiate between before and after LLMs. But regardless, there is a reasonable fraction of NNPPs — net negative productivity programmers.
@UweHalfHand @ludicity they existed before LLMs but maybe the fraction has increased.
@ludicity @davedave I do very much think so, just I haven’t directly seen that increase yet.
