Population growth is slowing down rapidly, there's even a chance that the global population will peak in the next century (and this is due to people living in industrialised countries having less than 2 children per woman, not due to any global calamity). We may have one more doubling of the global population, and then it's pretty much flat, even decreasing. Very, very far from exponential growth, that's for sure.

On the other hand, technological improvements aren't exactly stalling. In food alone there are huge benefits yet to be reaped from GMOs and hydroponics, just to mention two. It may not be exponential growth anymore, but there's little to suggest that it will just stop.

So no, the Malthusian limit may very well not be there at all.
