I hear this stuff alot since I am still going to school while employed as a developer. Strange, odd and sometimes downright incorrect sayings like "INSERT and DELETE sql statements are almost never used in the real world" from professors all the time.
It seems the less experience a professor has, the more they want to go on and on about "the real world" and how things will be different.
I once had to listen to a 30 minute rant from a professor teaching a db class that said "In the real world, tables always have prefixes, this book is awful because it doesn't have prefixes on any of its tables".
Ah, I revised the title, so the question is: What have you heard about "the real world" from academia that is completely incorrect?
Also, I'm not trying to bash academia or professors in general. As with everything in life, you'll experience those who are "amazing" to "awful" and everything in between.
For something thats gotten so many views, maybe it should be reopened :) Ah, 3 votes left!
