Robot Brains are Superior Background Data 1
Humans are on the planet earth after about 12 or 13 billion years since the "big bang".
So, where are humans on a graph showing time on the horizontal axis and energy density per second on the
vertical axis as follows:
What you see in Kevin Kelly's copy of Eric J. Chaisson's graph is the log-log graph of energy density in
Ergs per Gram per Second.
Note that in 2001 Eric J. Chaisson published his book:
Cosmic Evolution : The Rise of Complexity in Nature (Harvard University Press, 2001)
On page 202, he writes:
"A modern desktop computer [2001 vintage] can do more things, and quicker too, than could an old
room-sized mainframe because the former is more complex; the central processing units of today's
 personal computers have emense throughputs of both information handling and free energy
rate densities, a not altogether surprising result since these two quantities are clearly related.
Furthermore, the chips' phim values exceed those of human brains because computers number-crunch
a lot faster than do our neurological systems. That doesn't make today's microelectronic machines
more sentient than humans, but it does make them more complex, given their extraordinary functional
data-processing speeds. On the drawing boards now are advanced technologies for increasing the
number of transistors on a single silicon chip to the order of a billion, probably along with a continued
rise in Phim, all aparently attainable withing the early decades of the twenty-first century. Our information
age will then likely continue rocketing upward, either successfully to achieve new heights of complex,
artificial things or self-destructively to ends unknown--either path an entropy-producer, the result of
human-driven and Lamarckian-style cultural evolution."
Since he wrote that in 2001, there have been computer processing chips whose transistor count is
two billion, easily matching his prediction by 2010. The ten years between 2010 and 2020 will see
another 1000 or more times the performance. Don't forget that chips have been mostly two-
dimensional up until now and that the 3D chips are on the drawing boards. Plans are to stack chip
structures and to provide small tubes to carry liquid coolant.
