They probably saw that report years ago of copilot dumping out the fast inverse sqrt function, and assume that's all they can do. From experience most anti-LLM people have either never used them, or used them back in the 3.5-4 era and then never again, though you might have even more experience with those people than I do. :P
I am using LLMs daily and I am a Claude max Subscriber. I neither saw any reports about Copilot Dumping sqt methods.
Now that we established that everything you said is wrong, do you have other toxic opinions or was that it?
