A relevant snippet:

> This means that we feel comfortable about the prospect of allocating 178 billions /48 prefixes under that scheme before problems start to appear. To understand how big that number is, one has to compare 178 billion to 10 billion, which is the projected population on earth in year 2050

~So that's a maximum average 17.8 IPs per person? Seems awfully low, considering people these days have multiple devices connected to the Internet at any given time: phone, watch, tablet, laptop(s), perhaps desktop(s), security cameras, IP phones, refrigerators, washing machines, TVs, video game consoles, I could go on...~

Edit: oh, wow I misread that completely. It's 17.8 /48 ranges per person on average. Yep, that should be enough for quite a while.

Every phone gets a /48!
