He was at MIT in the crypto dept. among many other positions. strong background.
He's taught blockchain at MIT since 2018. Which is not very long. I'll ask you, too: do you have any idea how large, and how diverse, MIT is?
Oh, and obviously, he never taught full time. He's kinda busy with the SEC gig.
And what I originally asked is whether you've ever even bothered to READ anything he's written about crypto.
