Have you read the requirement of Tier 1 General Exceptional Talent[1] at all? I am reproducing them below. Do you think everyone who wants to come to UK should start on the path of either becoming a public speaker or start working on some sort of public platform to get recognised into these two categories.

You can apply for a Tier 1 (Exceptional Talent) visa if you’ve been endorsed in your field in science, humanities, engineering, medicine, digital technology or the arts as: 1. A recognised leader (exceptional talent) 2. An emerging leader (exceptional promise)
