LLMs lack judgement and vision
Many say models handle routine work well but fail at big-picture architecture, research taste, and tracking system state, impressing mostly outside the user's own expertise (Gell-Mann amnesia).
Math results prove real novelty
Others point to the recent wave of AI-solved open math problems as genuine novel work, arguing it is guided reasoning rather than brute force.
Novelty is recombination anyway
A middle camp says human ideas are also derivative, so LLMs connecting disparate knowledge at scale counts as useful novelty, especially with good harnesses and steering.
