I admire the parents who have kids who are off the charts and strive to help them be kids. Braxton might well have been better off at a top boarding school.
I too doubt that Duke TIP singled Braxton out as a one in a generation person.
Even the story about debate is suspicious. At the upper echelons debate is a highly structured and competitive activity. Results are documented.I searched and could only find one story. He and his partner won first place at a local high school tournament. They went 4/1.
After he finished Harvard Extension, Harvard changed the rules and now requires a high school diploma to enroll.
Back in 2019 Above The Law ran an article on him. He did apply to top law schools and as of the time the article ran he was waitlisted at Cornell Law. He said he really wanted to go to Columbia.
I wish him all the best, but I see no evidence he is a one in a generation kind of mind.
