I wouldn't call the ai-class.org platform broken. It's just not done yet. The AI class is like a beta test and there are plenty of bugs and problems. The content is still good, but the programming problems and automated grader that would be necessary for students to really absorb the advanced material doesn't seem to be on their radar. The result is a certain superficiality. The ML class is much more developed. In the first few weeks the contrast of the finished, professional seeming ML class with the rough and hacky AI class was extreme but AI is catching up. I'm looking forward to improvements in both platforms and new material in the spring. Other competitors like Kahnacademy are exciting, too. I'd like to see more study groups around the world building this into a movement with broadening impact. Neither class had direct support for forming study groups. If you have to go on Reddit to get together with people, you're excluding 50-90% of the people who would use a simple no-friction geo-aware meetup-style tool if it were on the site's front page and main menu. Since study groups have a minimum size threshold to remain viable, that eliminates a magnified portion of potential participants. So I'm pleased and still hope that this could be a mass-movement that leverages technology to change the way education is done around the world. Competing platforms is a better bet than one great platform for perfecting hard to build but needed features like labs, programming assignments, study group support, office hours and teachers' assistants, and homework help and hints. The future, at least in our industry, is bright.
