It still hasn't been shown that the world is anywhere near its ultimate carrying capacity.It has always appeared that we are overpopulated probably even when there was only 10% of the current population.Humans are but microbes in the great scheme of things. Current problems are all to do with poor government, corruption, banksters, the usual.
I'll believe that we are overpopulated when every town and village is permacultured and there are still starving people. Till then I'll just take these predictions as softening us up for the eugenic fantasies of the elites.
"Ehrlich and the others were early with their predictions."
Early in this case is just a fancy way to say wrong.
