Re: Why the comparison with wifi?
Yup.....two groups of folk are just salivating at the idea of pervasive 5G and IPv6:
1. Mobile providers (more $$$)
2. GCHQ/NSA and all the other bad actors out there who will be able to see much of the traffic currently behind a NAT.
About item #2 -- how long before laptops and tablets and printers and televisions are being sold "5G-enabled" -- so no one ever needs a LAN again?
