Earlier quoted context omitted.
As an unfamiliar, I find it interesting how you specifically called out physics grads in the pre-LLM era. Is that just snark or is there some widespread truth / stereotype of that behavior?
Physics, and to a large degree pure mathematics, has attracted a critical mass of the personality type that needs to feel like the smartest person in the room in any given situation. It has given them a slightly notorious reputation in academia.
(And it got so much worse once they started using LLMs to aid them in their efforts. Glazing as a service is a hell of a drug.)
So much easier, now that I am a lowly software engineer and can't be held responsible for a certain class of decisions, to just step back and let them be wrong.
