“Why not just use Lean?”

The author discusses the formalisation of mathematics and the rise of Lean, but notes that it's not the first system to achieve this. They mention AUTOMATH, which was developed in the 1960s and 1970s, and other systems like HOL Light and Isabelle/HOL. The author argues that Lean's success is partly due to its user community and the abandonment of "constructive proofs".
