Only a tiny minority of people have to look at those addresses, the majority just types "facebook", enter, clicks on first google result and gets facebook (because ".com" is too hard to write).
At best, I remember the prefix of my private network, and a handful of single-number suffixes of important hosts (i.e. my LAN is 192.168.1.x, and I remember that .100 is my local file server...)
This was discussed in the early 1990s. Criteria that were to be used for selecting then-IPng (§5.1: 10^12 / 2^40 was the minimum):

The winning proposal, SIPP, was originally 'only' 64 bits, but it was decided to go to 128:

> I know its stupid, but ipv6 addresses are just so hard to remember and look at that I think its just human nature to gravitate towards the simplicity of ipv4.
If only there was a system that allowed for easy to remember human labels to be translated to a machine-usable sequence of bits that we call "an address"…
Yet again, another fundamental misunderstanding (either genuine or not, I'm not sure) about the low-level technologies and their origins that underpin all of this. "Can't we just..."? No.
