If so, please explain.

Nobody dies. New people are produced, who don't die. Mortality rates keep population expansion from being exponential.

We can grasp a very limited understanding of but a very few advanced technologies we'll have 100 years from now. In that time span Earth's population may multiply seven fold. How many thousands of years would it take to grow exponentially and what technologies would we have invented? Considering the curve technology is advancing on we may be creating universes. If so, that's one thing volitional/conscious beings living elsewhere in the Universe are most probably doing with their greatly advanced technology. 

Volitional/conscious beings that live with integrated honesty will always solve the problems that thwart their immortality. They would never initiate force, fraud or coercion against any person and certainly not forced nonfertility.

Every volitional/conscious being living with integrated honesty is a huge benefit to civilization and produces more values than he or she consumes. Furthermore, when living forever is really forever each person will eventually create/produce more values than all values combined that were present at their time of birth.
