Adding A-F to the 0-9 existing digits in ip addresses makes them non-human readable? Give me a break. We've had something human-readable since the dawn of the internet: it's called DNS and works with both IP families.
Sometimes we need to deal with raw IP addresses instead of abstraction layers, and IPv6 fails hilariously because it clearly goes beyond the realm of direct human consumption.
You saying a non-human readable thing is human readable if it's passed through an abstraction layer to make something human readable only reinforces the argument IPv6 is not human readable.
