Yes, they will probably help you weave some html/css or understand CRUD apps, but I've yet to see one that will be helpful in understanding more than the basics. Smart people will certainly use this as a springboard to get in on the game and will learn more as they go along. But, depth in terms of debugging problems, knowing how to connect technologies (or craft your own solutions), scaling and the like take time.
I don't think we are at the late 90s stage of "you're a warm body? here is a job", but quick paths to coding, every tom, dick and harry being an angel investor, and the like do give me a pause.
I hope people do learn, contribute, and grow, but...questions persist.
