Will people really tell the difference between on a snowing beach with a sad princess and a neutral expression genie, versus on a snowing beach with a sad princess and a happy expression genie?
Because: (EDIT: Unfortunately, HN seems to strip emojis).
1..n..8 characters, assuming 1000 emojis, is somewhere ~along 1000^9 bits of emoji.
16 skies is 16 bits of entropy.
32 scenes is 32 bits of entropy.
You multiply those together, and you get 5.12e29, or 2^98. That is considerably smaller than 2^256.
-----
To get to 2^256 bits of entropy with an emoji set, you need 25 emojis. That's very long. That's like (HN stripped emojis).
Can you tell a difference between that and ? At a glance?
