I'm sure that when this was copyrighted in 1964 the author was proud of how up-to-date and modern our country was. That's nice.
But now it is 2007 and we have laptops and i-pods and printers and fax machines and cell phones and hybrid cars and we are making gigantic islands in the middle of the ocean where there used to be nothingness! I just thought it was funny that the book was talking about how "modern" we are when we think of all of the "modern" things it talked about as old-fashioned. I mean, If someone made a book nowadays about how things change it would list as "old" all the things that this book lists as "modern".
