I was reflecting just now (and I don't really know where it came from; I just woke up in the middle of the night and it was there), that our very common response to a problem (for instance, "Why is a a laser red?" or "Will a Wii play DVDs?") is to Google it (probably through your iPhone).

So much so that "to google" has become a verb, from the proper noun ("Google").

What you invariably find is that someone has asked the question before, in some form or other.

Anyway, the extreme rarities of the Googlewhack actually goes some way to proving the truth of the statement: "There is nothing new under the sun." (Ecc 1:9).

Humans think the same things. Humans ask the same questions. Humans don't innovate; much as there is innovative thought over the course of human development, most of our thinking is repetitive and cyclical.
