I am not, but there's a tendency among those types that categorise people into narrow sets that they can understand. Also your statement doesn't much make sense. Being a good developer means you understand a wide range of issues, not just spelling in a language and adding if statements. The combination of personalities vary wildly. To be fair, LLMs if anything, will help developers become better managers, simply because developers understand what needs to be done. Instead of decyphering what someone meant by requesting a vague feature, you can ask a statistical system - an ai as some call it - what the average joe wants. And then get it done.
Yeah usually it was the shittiest managers I ever met that shared this belief. It sounds like they all repeat the same thing - gpt is a better google.
