I took the AI class, and I also saw a degradation of the difficulty. At the beginning it was great. I even undusted my old 48SX, and had lots of fun: they actually made me think. But some of the lessons towards the end were almost a joke: I sure don't need to spend time applying a trivial formula back and forth, as we did in the computer vision lessons (deriving it would have been a slightly more interesting exercise.) I don't know if Stanford students were paying for this, but I'd not be very happy if I had. On the other hand, I am very happy that they are doing it, and I intend to take as many as my time will allow. And I wish they'll figure out a way to charge a small fee for having "Stanford" in the title in some manner, so that they don't have to spend about half of the certificate of accomplishment making sure that everybody understands that this is _not_ an actual Stanford certificate.
