I think blaming their attitude is going a bit too far, but the course definitely lacked a lot of what made the other two so great.

I started taking all three but dropped AI after a couple of weeks. I could have gotten over the software problems but the quality of the content made it difficult to keep going. The worst thing for me was the quiz questions. Rather than having one or two review questions per 20min video, the AI class seemed to have tedious homework style questions every two minutes. It was more of an annoying interruption than a useful addition.

Still, it's great that this exists, and I hope his experience with AI-class leads to improved content in these new classes.

There's also going to be more online classes offered by Stanford/Berkley starting soon, e.g. http://crypto-class.org./

The standard client makes it very clear that your wallet is nothing more than a private key (presumably because it's marketed to nerds who understand what that means). This issue has nothing to do with bitcoin itself, and there's no reason why you couldn't make a more user friendly client that protects the key for you.

This is true, but there are also plenty of reasons why a candidate wouldn't have a decent portfolio they could present to potential employers. The stuff I tend to do in my spare time tends to be rushed and experimental. I have a lot of unfinished projects, and the ones that do get finished tend to be the smaller things that I code on a whim without any intention of ever modifying it again, stuff done for programming challenges, etc.

Thankfully none of this reflects the code I produce in my working life, where I'm working under a different set of constraints, and have actual requirements to meet. The article specifically mentions experience on projects with actual users for this reason, but I think it's unreasonable to expect this from all graduates.

Technical/general problem solving questions aren't perfect, but relying on any one metric to assess a candidate is insane.

Not to mention NASA accidentally deleting THE FRIGGIN MOON LANDING! I guess with that specific example the cultural/historical value would have been a bit more obvious, but they were still routinely overwriting old recordings to save money.
