Opinions against the PhD, from an incoming PhD applicant

Mathematics is beginning to face a turbulent age due to the rapid advancements of AI systems.

AI and the mismeasure of science

Before AI, writing papers and grant applications served as costly signals of a scientist’s ability. Today, they can no longer serve that function. The time has come to return to illegible, subjective human evaluations of scientific quality. Rate-limiting authors is a necessary first step.

Applied mathematics has met the machine before

Why does AI worry applied mathematicians less? We have met the machine before: human computers moved up to designing algorithms, and a computer run led to the solution. Driven by problems rather than great conjectures, we expect AI, used with careful verification and validation, to make us better mathematicians.

Some Mathematician. Some mathematicians don’t use LLMs at all. Some others use LLMs and desire to state which models they use in their papers.
