Learn English – Is this an example of personification

Note that personification is not really the attribution of human characteristics to abstract ideas; it is instead the construction of a fictional paradigm who represents or embodies abstract ideas, as in the blindfolded female figure that represents Justice, etc. This is a small but important distinction.

Personification may also refer to a person who embodies or epitomizes a certain quality, or concept, or even a thing, as in "Winston Churchill was the very personification of wartime leadership."

personification - A trope or figure of speech (generally considered a type of metaphor) in which an inanimate object or abstraction is given human qualities or abilities.

English possessive - Nouns ... form a possessive with the suffix -'s ... sometimes called the Saxon genitive, reflecting the suffix's derivation from a genitive case ending in Old English.

genitive (also called the possessive or second case) - the grammatical case that marks a noun as modifying another noun. It often marks a noun as being the possessor of another noun; however, it can also indicate various other relationships than possession.

It would be ridiculous to say that when we refer to the river's edge, for example, we're assigning human qualities to the river just because it can have an edge. And with, say, a day's work, it's hardly even possible to think of the day as "having" work. The possessive apostrophe doesn't necessarily imply "ownership" - often it just denotes some kind of association.

OP's "related" question presupposes the false idea that possessive apostrophe = personification.
