Yeah, 4 million years of various “humanoid” species cohabiting & barely making it through (one big event wiping out the whole species - that’s why we have such a shallow gene pool & all look “identical” relative to difs in other species).
But the rapid growth was always unsustainable, the gens lived on natural wealth that they just took out of (into?) the economy way quicker than the replenishing cycle. But the difference between a million and a billon is unimaginable, that’s why we can now witness the collapse (mass extinction event) within a generation.
