I was on the train to Portsmouth, and listening-reading the book “In the Plex”. In the Part 2 of the book, Chapter 2 if I recall correctly, the author is talking about Google and the Ocean project, what is later on going to be know as Google Books.

The part that got me thinking is when Page, Brin and Mayer are trying to work out how actually they can scan the physical books, in a scalable manner. To the Googlers, hiring a lot of human beings and a lot of scanner didn’t look like a scalable solution at all! So they decided to work on their own scanner, using the hardware building expertise that years of Google Data Center made them acquire.
