Want to take an online course at Stanford on “how to build a search engine”? You’ll soon be able to…

Take the “Introduction to AI” course, for example. […] 160,000 students signed up, from more than 190 countries, with a median age of around 30. But the really staggering thing is that about 23,000 of them stayed the course and finished it. A friend of mine, Seb Schmoller, took it and reports that it was worthwhile but pretty tough going. The project has been so successful that Professor Thrun has set up a spin-off company which plans to enrol 500,000 students on its first two courses: “Building a search engine” and “Programming a robotic car”.
