It would be like telling someone who has been using an IDE: did you know you can compile your code from the command line? And having that person genuinely be blown away.
would it blow your mind to know that the vast majority of .net devs I've ever worked with don't know anything about compiling or running a project/solution other than hitting that big green 'play' button in visual studio?
The hell happened? Did I get cryogenically frozen and just woke up?
