I wonder if Wifi 6 will end up being a competitor to 5G (in urban areas), given it (supposedly) increases both the speed and bandwidth that 802.11AC offers, while also improving efficiency. I heard that a certain cable / internet provider plans to shift away from the current pole to home coax system and go to wifi-based pole to home distribution system, which makes sense. It also then provides more options for wifi coverage within cities they serve, both for streaming services and phone / communications.
Rural areas are unfortunately always going to be the last to get up to date tech. I used to have a business in Northern Wisconsin where there were times that I didn't have any cell coverage, or just terrible 2G connectivity. But as soon as T-Mobile decided to add some towers in the region, ATT and Verizon joined in and all of a sudden there was great LTE service. In fact, cell service was faster than the service we had at the plant (cable), likely because so few people were on the cell towers at any given time. That and even the cable internet was SLOW up there. Of course, there were benefits, including being forced to slow down how you live and work.
