Top 3 Lean Lean Projects

The author is quick to dismiss dependently typed languages, which indeed solves the issues he describes. I think we will someday see a mainstream dependently typed language, Idris is one candidate and Lean 4 another. However, the issues described in the post are quite rare in practice, and macros are a good enough solution in many cases. Type systems like Rust's gets you 90% there when it comes to abstraction and static guarantees (and maybe 95% when you add macros), to get the last 10% you need to complicate the type system a lot.

Project mention: Why is simplicity so unreasonably effective at scientific explanation? | reddit.com/r/slatestarcodex | 2021-10-13
No, they really are - you've just internalized the vast majority of the content already. This is what a moderately careful (Lean makes some mildly questionable compromises regarding quotients) attempt at building up calculus from first principles looks like. And this is still assuming quite a bit of foundation. Human beings are much better at math than a bunch of apes barely down from the trees have any right to be - but that doesn't make math any smaller.

Lean 3 introduced singleton-elimination which is inconsistent with HoTT. There's a project [0] that uses an attribute to restrict uses of that rule, but it isn't really ergonomic to use.
