OP should have put "engineers" in double quotes. Many software developers like to describe themselves as engineers although they don't have an actual engineering degree. A lot of software development resembles plumbing more than engineering, so most devs don't really need an engineering degree anyway, but they should be more honest about what they're actually doing and not try to elevate themselves with fancy titles.

You are, of course, right that the idea that someone could finish a serious engineering degree without being able to think is ridiculous.
