Both are unlikely in practice imo, because they make an N-of-N assumption. If even one culture can keep fertility rates high while others go low, it will end up dominating population-wise. If even one culture can continue to focus on the physical world while others go virtual, it will end up dominating militarily.

You can live in virtual world and control robot within the real world. Simulation has unlimited speed but real world experiments have async await
On the former, it is striking how fertility rates are crashing globally across very different cultures -- America, Europe, Japan, Korea, China. On the latter, we may be entering an era where technology + money matter more for military supremacy than men + materiel.
