I read a recent analysis and the "wild card" that seems to be making the
Simons right and the Erlichs wrong is technology (driven by human ingenuity).
The geologists are figuring out how to get more of the oil out of the
ground and still aren't getting a large fraction of it. So there is
substantial room for improvement.
If the plans the U.S. DOE has on the board for electricity production
get implemented over the next 10-20 years then I think the problem
is solved. Everyone knows we have several hundred years of coal
resources and the electrical production efficiencies are slated to
jump from ~35% to >80%. Several hundred years give us plenty of
time to switch to solar power and/or fusion. Cheap electricity lets
you switch to hydrogen as a locomotion fuel for most applications.

"It clearly is"? Basis for assertion please?
Take a look at 3D printers. What is there that is so hard to grasp
about the concepts of self-replication, exponential growth and the
concept of turning matter into "software"?
I will not argue that it *will* be complex. You aren't going to
design the precise location of every atom in an 18 billion atom
nanorobot yourself. You are going to write the software that does
much of the work and actually directs the assembly process. But
I've made the point in my Nano@Home paper -- the problem isn't
with the assembly process -- it is in having the designs. If you
look around at all the nanomachinery we currently have (also known
as "nature") its clearly going to be a big job designing the equivalent
and more -- but it doesn't require a great deal of actual
"intelligence" -- it simply requires the ability to create
and recognize good designs.
