I think structured learning is useful for many - the sad part of being an adult is that for most people, their lives become driven by responsibilities instead by curiosity. Sure, you may want to learn programming (and maybe you even have a good economic reason for that), but there are always "more important" things that need to be done right frakin now. Some people are good at self-organizing and can cut out time for learning, but for many, having an external entity create and enforce a structure for learning is a good way to hack one's problems with prioritizing stuff.
