If you register, you can view the transcript, but unfortunately it is broken up by video so you can't view the whole thing. And it's unedited, so the stuttering is part of the text.

Edit: Knew I had seen the full text somewhere, managed to find this: https://github.com/kragen/knuth-interview-2006

Wow, even the transcript is hard to follow. I wonder if he wishes he could edit it himself, since he is a writer too.

Thank you!

Especially with Mister Knuth, he's borderline stuttering sometimes; hard to follow.

That's not borderline. He certainly has a stutter. I've seen it in all the videos I've ever seen of him. It's a shame seeing someone with such an impressive mind having trouble expressing himself verbally.

His vocal system can't handle his own brain bandwidth I guess.

He uses his brain and language so effectively that some parts of the sentence can actually be used as padding.
