Knowing the application is not important. What's important is having the connectivity, bandwidth, and latency. The applications will follow. The applications that people currently use most would not have been possible 15 years ago. Facebook? YouTube? Instagram? All completely impractical in a time, not that long ago, when 1.5 Mbps T1 was "fast." What I find most infuriating are the many people who justify current speeds (and prices!) by rationalizing that they don't use all that much bandwidth, anyway. Almost certainly, they're using more bandwidth than they were 15 years ago. If they have more bandwidth, I'm sure they can find a use for it. The worst for me is that gigabit fiber exists, but is usually not available. In 1900, telegraph was the lowest-latency way to communicate a long distance. (Never underestimate the bandwidth of a steam train full of mail hurtling down the transcontinental railway.) It was the best there was, and it enabled a revolution in communications. Now, gigabit fiber is the best, but it's uncommon. Instead, the telephone and cable companies would rather reinvest profits into lobbyists and mergers.
