Of course. I'll agree anything that gets kids to self-teach is good, as that's the real problem of education (in other words, no desire to learn for any reason)

Of course. I'll agree anything that gets kids to self-teach is good, as that's the real problem of education (in other words, no desire to learn for any reason), and this approach apparently has experimental backing from you and the paper. I just don't think this should replace standard CS, but rather be something separate; call it something like Elementary Programming, and probably encourage it more than standard CS.
