Perhaps someone who actually has an inkling can give us a heads-up as to where the technology will be in 5 years' time.
Frankly I haven't a bloody clue about anything in three months' time never mind 5 years. By then all of this will be irrelevant.
I already have 5G (not in the UK) and I do not care.
By the way, you do know that China - probably the most wired-up (i.e. wireless) country on the planet - is forging ahead on a number of fronts apart from 5G - A.I, for example? The domestic GDP per capita is now such that economic and technological advances are self-sustaining regardless of Trump's attempt to roll the clock back a hundred years,
