Everyone knows that and wants to migrate towards a virtualized stack, and has been in the process of doing this for at least 15 years now, but you are faced with some very hard accounting questions around how to eat the financial cost of deprecating legacy (physical) infrastructure without incurring a massive financial penalty. It's a hard problem, and countries like SK, China, and India weren't hit by it because they are greenfield deployments. It's similar to how Germany and Finland lags in fiber because they went gung-ho very early in copper broadband back in the 90s. It's a ridiculously complex system. (And that complex system is increasingly being replaced by equally complex K8s, but it makes sense given the dynamic scaling that comes with telecom)
