It'll be interesting to see what happens if 5G doesn't fully live up to its promises (that is, something like speeds ultimately not being much better than the current options and/or pricing not really decreasing despite additional "competition"). Will that end up forcing the country to finally roll out fiber to a much wider extent than has already been done?

BTW, the most annoying part IMO: AT&T Fiber is actually available in some parts of where I live. However, they hit the 11 million or so availability number the government required as part of the DirecTV deal prior to reaching my neighborhood, so they stopped expanding it further. In fact, they put up what looks like a mmWave 5G cell on the light pole outside of my condo complex and actually ran fiber just for it (and not the U-Verse cabinets next to it); it seems like it wouldn't have been too much more effort just to convert the people using U-Verse in this area to Fiber.
