here lies the issue. there went a whole lot wishful thinking into the so called 'use-cases' which were somehow instantly translated into prediction by the media (and vendor's marketing core) with the 'fake it till you make it' mindset from day 0.no matter how low latencies are in a lab setting.
on the other hand, in real world physics is still a thing, and the speed of light in fibre optic cables pretty much declares how much latency one will have over 100km distance, like it or not. daydreaming about sub-ms end-to-end latencies and showing off at MWC - regardless what pay grade are those execs in - tells just this message: "we have no clue what i'm talking about"
