I had to explain this to a programmer who hadn't used a pillar drill before.
I said, "We should use strings for everything! All data should be stored in String format!"
Reply came, "You can't do that! There are times when strings are useful, and there are times when they are the worst possible tool to use."
I looked at the drill bits, then showed them the difference in results on scrap material... :D
No matter how brilliant you are in one field, you are a novice in many others. :D
