I don't think anyone argues that advancing the state-of-the-art makes
sense. It's just that the issue is at what cost, particularly if today's
technologies are relatively well deployed, well understood, are up to
the task and are affordable?

Fibre has been around a long time, but it wasn't affordable to run to
the home until technologies such as PON and bi-di optics. Electric
vehicles have been around a long time, but it wasn't affordable to own
one until there were significant advancements in battery storage and
hybrid technology. Studios have had HD video capability for years, but
it's been trickling into the consumer space years later. MPLS has been
around for ages, but it's only in the last 6 or so years that it's been
affordable to run it all the way into the Access.

No one argues that 5G will move the industry forward, but at what cost
if deployed right now? Moreover, 4G/LTE isn't struggling, wi-fi has made
leaps and bounds now with 802.11ax, and there is more fibre into
businesses and homes than when we had 2G and 3G. So while no one argues
that the case for 5G is there, it's just a bit harder to make when you
look at the entire picture as things stand on this 3rd day of 2020.
