Thrun’s ultimate mission is a virtual university in which the best professors broadcast their lectures to tens of thousands of students. Testing, peer interaction and grading would happen online; a cadre of teaching assistants would provide some human supervision; and the price would be within reach of almost anyone. “Literally, we can probably get the same quality of education I teach in class for about 1 to 2 percent of the cost,” Thrun told me.
The traditional university, in his view, serves a fortunate few, inefficiently, with a business model built on exclusivity. “I’m not at all against the on-campus experience,” he said. “I love it. It’s great. It has a lot of things which cannot be replaced by anything online. But it’s also insanely uneconomical.”
