Then:
“About every year and a half, someone invents a new chip that does twice the work of an old one and costs half as much. By the year 2000, you may be able to buy an inexpensive book-sized computer that will store all of the information in all of the books in the whole Library of Congress”

Now:

Today we have the iPad and other tablets, capable of accessing every piece of information ever written. As of 2014, the commercially available processor processing the highest number of transistors is the 15 core Xeon Ivy Bridge-EX with over 4.3 billion transistors.

Fast Forward:

Eventually transistors will reach the limits of miniaturization at atomic levels bringing about the entrance of nanotech transistors capable of manipulating matter at a molecular level.
