And how many years this will last? Mind you that while some countries are already solely running on 4G, there are other countries still having a large 2G phone usage and large 3G data usage. It is only fair to compare it to this - otherwise it would be unfair to those who rely on older technologies to connect to the world. I need to point out that I do not really disagree with RCS' intent - but Google aggressively trying to promote RCS outside of commited carriers is not just weird but can be dangerous.

We can't keep supporting old tech in new world. 2G and 3G is already two decades old, we gotta move on. And I am not talking about killing SMS. 2G/3G will still support SMS, only 4G/5G has to adopt to RCS and use SMS as fallback (like it already does) Having RCS is still better than being in current situation where you're locked into Whatsapp/iMessage/Some proprietary solution from a carrier
