Grading systems in school are and have always been broken, ChatGPT is only making these issues more apparent. Students are great "reward hackers" and are incentivized to find the most efficient solution to getting good grades regardless of whether they're actually learning. Learning takes a back seat to getting good grades.

There's a reason you're only hearing this from schools and not companies. I haven't seen any corporate execs complaining that they don't know who their good and bad employees are because of AI.
