Not really. Just a prediction about the future and as the infrastructure takes years to build out better to start early than late.
Bandwidth usage globally has been growing at around 30% per year for a long time now with nothing showing it would slow down (obviously not all of this is wireless). LTE will sooner or later run out of bandwidth and thus 5G basically allowing more mpbs on the same radio spectrum (and also rolling in new frequencies)
Even today in relatively low population density country like Finland (where I live) LTE connections in cities are slower during peak hours due to the radio frequencies just being full. (In general most plans have unlimited data so people use them a lot)
