Population growth has overall largely been a function of increased energy availability, from the industrial revolution onward through the consumption of fossil fuels which are inherently unsustainable.[1]
Also, assuming the number is for example 100 billion, it seems like you still have the same issue of infinite population growth being inherently unsustainable but just on a different timescale.
