From Aristophanes, (we are assured by a confidential informant of untested reliability), the ancient Athenian comedic poet and playright:
Youth ages, immaturity is outgrown;
ignorance can be educated, drunkeness sobered -- but stupidity lasts
forever.
Which reminds me that I have an investigator, Holmes, affectionaely called Sherlock, of course, who said of a man who, if he didn't
commit the offense with which he was charged, committed one that was
indistinguishable from it:
There's no defense
against stupidity.
However it may be argued in mitigation.
Let's see, there's also:
Beauty fades, stupidity is forever...
What we lack in quality, we make up for in stupidity...
A dream lasts for a night, but reality lasts forever...
Digital information lasts forever or five years -- whichever comes first.
Altruism is the reverse, and stupidity is where both sides lose.
And last but not least:
Computers can never replace human stupidity.
