I cursory read the FAQ, somewhat funny that it's a series of questions with a "no" answer, that made me curious about the author, so I looked for public speakings on YouTube. Right now the first hit is a 18 minutes presentation of this book (so I think as I haven't watched it yet) called "(sixth RacketCon): Matthew Butterick -- The Making of “Beautiful Racket”".

I thought that someone else here could be interested...

edit: clarifications
