 Yeah, well 1, 2, 3, and 4G have all been super important in the transition of mobility and all have been, in a sense, changed the way we work and we live. 5G is a different breed. 5G will bring incredibly powerful speeds, but in a way that's super low latency meaning it happens very, very fast. So the use cases that we can do with 4G, which we use today from a societal perspective, change greatly as we move to 5G. 4G will be here, but 5G really just changes all the use cases completely. Think about things that required fiber that don't require fiber any longer.
