We're still in the trail-blazing phase of the game, folks. It's gonna be spotty, sparsely populated, and not immediately apparent what the point is in the early going; sort of like settling the untamed frontier.
But given time, it's going to be ubiquitous and unrecognizable compared to its infancy. It's like driving the Interstate where there were once two parallel ruts worn by Westward wagon traffic. And we'll be the grumpy old timers telling the young'uns about the time when 4G was something you had to travel to find, uphill in the snow, both ways.
