I'm seeing lots of engineering students now who don't seem to be bothered at
all about not knowing the first thing about what they're doing, even in
fourth year, but who still expect to be given a degree with all the rights
and privileges pertaining thereto. It's probably the single most
frustrating thing about being an engineering professor today. Of course, in
most cases, they are getting those degrees. Once the university takes the
view that students (and their parents) are "customers" and that professors
are "service providers" rather than gatekeepers, it becomes very difficult
to fail anyone.
