I know it's against the rules to be a curmudgeon, but this just reads like a lullaby for people preparing to drink the SF kool-aid. The opportunity cost of becoming an expert will remain, but the reward of pushing the frontier is mostly gone. Now, if you want to save universities as institutions(*), you'll have to offer people some other positive vision. "You won't be able to make a difference" is not one of them. After all, you can get understanding for the joy of understanding (doesn't seem very egoless to me btw) outside of academia as well.
I'm much more sympathetic to the views of this anonymous postdoc here: https://proofsandprompts.com/2026/10/22/the-rules-cannot-cha... (unfortunately also in LLM-"polished" English). Quote: "A field that fails to attract and support its next generation cannot preserve itself through inspiring statements alone."
(*If you extrapolate a little, for now you can also substitute with 'math departments' there.)
