At least now instead of just theory we have one study of the results and a data point to use in the next attempt at a similar project. The idea is probably still solid and could be attempted again but with a more refined implementation.

I don't think you'll find a deeper study than this. And not everything was bad, at least one benefit was "significantly improved students’ computer skills" which may help them get employed in the future, the study focused mostly of academia but there is a whole world outside of academia :)
