The part before "But seriously" was sarcasm. I find it very odd to assume that a professional developer (even if it's not what they would describe as their field) is using it wrong. But it's a pretty standard reply to measured comments about LLMs.

They're encountering a type of tool they haven't met before and haven't been trained to use. The default assumption is they are probably using it wrong. There isn't any reason to assume they're using it right - doing things wrong is the default state of humans.
