My concern is that students/novices are going to be using this, without the ability to double-check the output of the tool. It inspires overconfidence, looks okay at the surface level, and bugs go unnoticed. The younger generation using this as a crutch, treating their own creations as a black box, will not have an adequate feedback mechanism to learn from their mistakes. Code quality and performance will deteriorate over time. You, an expert, learned without this crutch. Your use-case is frankly uninteresting.

Amusingly, without careful curation, I'd predict that buggy code will tend to self-replicate and these tools that indiscriminately slurp public code will enter a death spiral because the novices outnumber the experts. It's only a matter of time before viruses are written to propagate through this garbage stream. http://www.underhanded-c.org/
