Exactly this. I look at the evidence provided here around how much farming land it takes to sustain each person I think that we got lucky. Through research we figured out how to sustain all these people with less land, without which by now we would have mass starvation and famine. But I also think that here in the US, we have less humans per square km than just about any other country, and we're doing just fine, in fact, we are contributing more than our share of new research and tech. There's no correlation here, let along causation.
