Lean 4 is not a theoretically-interesting proof assistant. If you're interested in such things, look into Rocq (which uses CoIC, like Lean, but is more rigorous about it), the HOL logic, Isabelle/HOL's automation suite (though Isabelle proper is fairly mediocre, apart from being the thing everyone's standardised around), Lean-auto (https://arxiv.org/abs/2505.14929), and whatever SAT solvers are state-of-the-art this week. Like the tools for symbolic integration and frequentist statistics, there isn't any magic: the power comes from handling enough uninteresting special-cases that we get broad…
