Guido van Rossum 在什么地方和什么情况下说 "If you want your code to run faster, you should probably just use PyPy."?

Where and in what context did Guido van Rossum say "If you want your code to run faster, you should probably just use PyPy."?

PyPy's main page 指出 Guido van Rossum 曾说过:

If you want your code to run faster, you should probably just use PyPy.

PyPy 的主页没有提及此声明的位置或上下文。他是在会议上和某人 face-to-face 交谈时说的吗?无论如何,周围的话题是什么?是关于 Python 的表现吗?

这是他在 PyCon 2015 上关于类型提示的演讲:https://www.youtube.com/watch?v=2wDvzy6Hgxg&t=16m52s
