I would think that it would grow even faster in the next 40, given the
logarithmic nature of the reproduction curve. It took thousands of years to
make it to the first 3 billion, and only 35 or so to make the next 3
billion...

Interesting point you make. I would like to see the metrics being used
for the projection, perhaps something we don't know about is being
factored in. Conspiracy theorists have at it.
