To say that students don’t benefit from getting good grades using LLMs is incredibly naive. Learning is only about the third or fourth most important “benefit” for students, after getting a degree, getting good grades, and making connections.
These matter about getting the first job you get, at which point what you learned begins to dominate the rest of your career and life. The connections you made at school matter less and less as your connections in your career dominate, and they are built on what you can do, which is based on what you’ve learned.
Does anyone look at GPA on a resume? I’ve hired thousands of people I’ve never once looked at GPA. (N.b., my resume has “summa cum laude” ok it and no one has ever once mentioned it or presumably noticed it, despite the fact you only really get it if you can BOTH learn the material AND get perfect grades)
