It shows that the issue is much broader and myopically focusing on how math PhD students will be evaluated etc. entirely misses the forest for the trees, it's just not even close in proportionality.

This is indeed also coming for law, medicine, and banking, though licensed professions will hold out for longer because you need someone to put in jail when things go wrong. The problem is that all this is extremely over politicized and nobody is able to think clearly. They want to simultaneously say all this is just hype and a bubble and will go away like NFTs did, and also are starting to worry about economic replacement. Some more coherent political narrative will have to be formed.
