I'd rather take a student who put the same effort into building stuff with OpenCV, Eigen or Simulink though. ROS teaches a bunch of bad architecture habits that need to be unlearned, and which many fail to unlearn. People can understand it's bad but then they still build a framework and a distributed system full of async calls to try to replace it, for example.
