Sebastian Thrun left his tenured teaching job at Stanford University after 160,000 students signed up for his free online version of the course “Introduction to Artificial Intelligence.” The experience completely changed his perspective on education, he said, so he ditched Stanford and launched the private Web site Udacity, which offers online courses. “Having done this, I can’t teach at Stanford again,” Thrun said. “You can take the blue pill and go back to your classroom and lecture to your 20 students, but I’ve taken the red pill and I’ve seen Wonderland.” (Thrun is staying at Stanford as a research professor, but will not be teaching there).
What exactly was the “Wonderland” that Thrun saw that sent him into such euphoric zeal that he discarded his position at a premier institution of higher education like he was trading in an old clunker at the car dealer? He saw those phenomenal numbers signing up for his class, and it made him dizzy with delight. Anybody with a Twitter account or Facebook page can understand the feeling. Your number of followers or friends can be a source of affirmation, proof that what you have to say is important. I was on Twitter for several weeks following anybody I found remotely interesting, and then someone told me that it is better to have more followers than followees, so I promptly started culling my list. I didn’t want to be a Twitter loser. But surely those adolescent impulses don’t affect scholars like Thrun.
