From Wikipedia on RoP:Nonsense. Even taking the articles implication that the 'maturity' is referring to an emotional maturity, and granting what can be told from from Amazons stated time (1000 years after the defeat of *Morgoth) and utilizing the most (I think) generous in Amazon's favour of the aging schemes of Tolkien, *Galadriel would be 20 at the rebellion/exile, + ca. 1600*/144 = @31 years old, not " little more than a young human adult"One more interesting curveball we have to touch on here is the concept of Elvish aging and maturity. In the book "The Nature of Middle-Earth," Tolkien breaks down a mathematical formula — yes, a formula — for how fast Elves mature. While the numbers are complicated, the primary takeaway is that Galadriel's maturity level is little more than a young human adult during "The Rings of Power" story. During "The Lord of the Rings," she's matured into an elder statesman. It seems that this lack of maturity in a younger Galadriel was present in the minds of the writers as they developed their younger iteration of the character for the show.
Utilizing the ageing scheme, *Elrond would be approximately the same age as *Galadriel.

Hostetter's "The Nature of Middle-earth" was published in September 2021.
That makes the comment quoted by Tar-Elenion from Jaron Pak's article among the most irrelevant and imbecilic mental diarrhea I have ever read from an apologist of the media trolls.
