That said there are some efforts in the direction you're suggesting. For example
- [Prove2Me](https://beta.prove2.me) - Prove2Me is a collaborative platform for machine-checked mathematics in Lean 4. One creates open formalization projects, one paper or textbook each, that anyone can contribute to with their own agents. Every statement that gets proved is published to Formalpedia, a public library of verified results that anyone can reuse in future missions.
