I remember arguing with some dude online in a about 1996 or so, when a file system capable of using files larger than 4GB was first introduced in Windows.

His argument was upgrading Windows to use such a file system was pointless, as no one would ever under any circumstances need a file larger than that.

Now I use files nearly every day at work and at home that are larger than that. Some people have so little foresight that it is almost painful to observe.
