Just to ask, haven't there been several reports of LTE/5G protocols being compromised, making the worst-case scenario one script-kiddie away from major disruptions? Why would they even contemplate building on a compromised foundation or worse yet, accelerating a roll-out? Since most of the tech from last century was built on trust models/trusted environments, waiting for a clean rewrite sounds like a better plan . I personally hope we see them build new 21st century cities and dedicated autonomous highways to grow driverless technology, instead of trying to overlay it on the existing horse and buggy infrastructure with time-period correct code/models. The world doesn't need any more digital diarrhea on its plate.
