In math, rigor is vital, but are digitized proofs taking it too far?

https://www.quantamagazine.org/wp-content/uploads/2026/03/FormalMess-crKristinaArmitage-Lede-scaled.webp
Mathematicians have long sought to formalize their proofs to ensure rigor and accuracy. They've developed systems like Lean, a computer language that can automatically verify proofs, but its adoption comes with risks of homogenizing math and shifting focus away from the problem domain.
The author built an NSFW filter for a search engine using a single hidden layer neural network, trained on a dataset of labeled search results. The filter was implemented from scratch and performed well, with a 20-30% agreement with a classifier using open-source models.
