Ha, agreed. I was training a new help desk employee a couple years ago (22 years old) and dated the shit out of myself explaining why I don't like spaces or special characters in file names and directories and why we want to try to keep them as short as possible.
So did I, but Macintosh people looked at it from an angle of "Why would you not put spaces in file names? They're meant to be human readable, and you will click on files more than you will type them in anyway." They were right, in the end. The future was less evenly distributed in the 80s.
