Why formalizing deep learning as a science could revolutionize the whole LLM stack

JoshPurtell · x · 2026-11-15

Josh Purtell argues that once the science of deep learning is developed and formalized, nearly every part of the LLM stack could be revolutionized — from architecture to pre-training to interpretability to RL limits and convergence.

His key contrast: in mathematics, LLMs must push the human frontier forward in abstraction and theory-building since math sits at the forefront of both. In deep learning, they can simply transfer meta-strategies from physics and math. Once DL becomes a formal science, all human and LLM efforts would be massively aided.
