What would make him greater than other fields laureate?

Beyond the incredible quality and quantity of his work starting from early in his life, what makes Terence Tao memorable to me, is his approachability and willingness to write advice for mathematicians and math students in a blog: https://terrytao.wordpress.com/career-advice/

He also has an active Mastodon, which further makes him more approachable: https://mathstodon.xyz/@tao

It's rare to see a professional at the top of an academic field remain so encouraging to other people in the field, and work to make their work accessible to colleagues across different levels of mathematical maturity.

Other mathematicians opinions of him and his work. He's very prolific and was considered a child prodigy.
