No, it's just saying "NOTHING" is written in stone -- which it obviously is here, on the first line.
The fact that "IS WRITTEN IN STONE" is also written in stone isn't mentioned, probably due to lack of space.
Yeah as the picture shows, nothing is written in stone is written in stone.
Likewise, nothing is written in stone is written in stone can also be written in stone.
And nothing is written in stone is written in stone is written in stone can also be written in stone.
etc.
Just a stone with “Nothing” carved in it would be an even more powerful troll.
Might get dug up too often by people assuming there’s something under it though.
It isn't, because "nothing" isn't put in quotation marks like I or u have. Quotation marks indicate literality which would be required in this interpretation. So no, the absence of quotation marks makes this statement contradictory and hence, wrong.
There is no period so it's not technically a statement, nor is it properly capitalised to be a statement. It is a title. Ipso facto, your rules regarding proper punctuation are null and void.
Fair. However, as a title, it is essentially just a string of words that collectively act as a noun, or a name for the given face of the stone. Names being names can never be right or wrong. Hence, we all are wrong for trying to judge whether this string of words is right or wrong as it is semantically impossible for it to be right or wrong. By pointing this out, I am right and you are all wrong.
If we're being pedantic, graphite is technically a stone, so things are frequently written in stone
