Alexander John Lee(@alexanderlee314):I haven’t been as excited about a programming language since when I first started learning Rust. Lean4 is an extremely powerful language. However, one thing it’s missing is good tutorials and examples! So I built an online Lean4 learning tool! I predict Lean becoming one of the most popular languages in the coming years amongst AI labs, blockchain researchers, and agents. It’s what powers verifiable auto-research. Lean4 increases the velocity at which humanity can make mathematical discoveries. To be ahead of the curve, learn some lean today! Open to feedback and suggestions! 😅
