Query: Why We Should NOT Talk about 6G   While 5G mobile communication systems are currently in deployment,
researchers around the world have already started to discuss 6G technology and
funding agencies started their first programs with a 6G label. Although it may
seem like a good idea from a historical point of view with returning
generations every decade, this contribution will show that there is a great
risk of introducing 6G labels at this time. While the reasons to not talk about
6G yet are manifold, some of the more dominant ones are i.) there exists a lack
of real technology advancements introduced by a potential 6G system; ii.) the
flexibility of the 5G communication system introduced by softwarization
concepts, such as in the Internet community, allows for daily updates; and
iii.) introducing widespread 6G discussions can have a negative impact on the
deployment and evolution of 5G with completely new business cases and customer
ecosystems compared to its predecessors. Finally, as we do not believe that 5G
is the end of our journey, we will provide an outlook on the future of mobile
communication systems, independent of the current mainstream discussion.
