Stop Shouting
THE FIRST RULE WHEN STRESSED OUT IS NOT TO SHOUT BY USING CAPITAL LETTERS......
Of course 5G will bring about a new wave of security risks, but then everything new in the last 15 years has brought about security risks. The difference nowadays is that we have experience and we now accept that risk is not "if" but "when". This means that we can do a modicum of planning, preparation and hopefully some testing.... None of this is new.....
Personally if they can really bring a serious bit rate to the market, without being maxed out every time you enter the city center, then I believe that 5G will bring about more good than bad... It might even alleviate some of the FTTH false promises....
