I was refering to your claim that "most STEM people thinking that their topic of interest can be widely applied and solve problems in other fields". I don't know any of my colleagues who thinks THAT. As for LLMs, they are a tool. People are still learning its limitations, sometimes the hard way.
When I was a student, a chemistry student complained to me that their philosophy prof failed them on their essay, because they used chemistry to argue philosophy. They said chemistry > philosophy, so their prof was an idiot. They were just a student, so maybe it's just the physics/maths/CS adults.
