Yet another developer who is too full of themselves to admit that they have no idea how to use LLMs for development. There's an arrogance that can set in when you get to be more senior and unless you're capable of force feeding yourself a bit of humility you'll end up missing big, important changes in your field.
It becomes farcical when not only are you missing the big thing but you're also proud of your ignorance and this guy is both.
