William Gibson
A MILLION SECONDS IS 11 DAYS
A billion seconds is 32 years.
A trillion seconds is 32,000 years.

I have crossed the 1,500,000,000 second threshhold. It looks like a lot and it feels like nothing.

Once upon a time, I dreamt I was a butterfly.
Suddenly I awoke.
Now, I do not know whether I was then
a man dreaming I was a butterfly,
or whether I am now a butterfly
dreaming that I am a man.
– Chuang Tzu (c.360 BC – c. 275 BC)

Here is a different translation:

I dreamed I was a butterfly, flitting around in the sky; then I awoke.
Now I wonder: Am I a man who dreamt of being a butterfly,
or am I a butterfly dreaming that I am a man?
