yes, this is the thing I'm not quite getting from the "malthus was proven wrong" argument. Yes, technology increased food production, but that doesn't mean there isn't a carrying capacity to the earth. We have overfished. Fisheries are in decline all over. I guess you could say "no problem, we'll have lab created or grown fish and it will be fine" ok, maybe. But it's not going to be the same and the oceans won't be the same.
What I don't get from all of the demographic collapse hand-wringing: Somehow in the 1970s we got by with 1/2 as many people as we have now - why would a long, slow decline back down to that number be catastrophic? Why would stabilizing at a lower population be problematic? Sure, during that decline there's going to be issues, but once you hit a new stable population those would go away.
