Nice benchmark but the human comparison is a little lacking. They claim to have surveyed 19 experts, though the vast majority of them have only a master's degree. This would be akin to comparing LLM programming expertise to a sample of programmers with less than 5 years of experience.
I'm also not sure it's a fair comparison to average human results like that. If you quiz physicians on a broad variety of topics, you shouldn't expect cardiologists to know that much about neurology and vice-versa. This is what they did here, it seems.
I'll get some downvotes for this but PhD vs master's degree difference is mostly work experience, an element of workload hazing and snobbery.
Somebody with a masters degree and 5 years of work experience will likely know more than a freshly graduated PhD
