translation.en: I didn't quit the Media Lab, I stepped down as chairman -- which was a kind of ridiculous title, but someone else has taken it on -- and one of the things you can do as a professor is you stay on as a professor.
translation.zh: 我没有退出实验室，我只是不再做“主席”了—— 这个头衔有点滑稽，不过现在由另外的人担任了， 当教授就是有这么个好处， 那就是你一旦当上，就一直是教授。
