The Lindy effect says that entities with longer realized lifespans have longer expected future lifespans.
In other words, if one thing has been around for 5 years, and another thing has been around for 3 years, then we know three things:
1: The first thing's expected future lifespan is f(5) years.
2: The second thing's expected future lifespan is f(3) years.
3: f(5) is greater than f(3).
Etheryte claims, in a gross error, that this does not imply that the expected future lifespan of shorter-lived things is shorter than that of longer-lived things. This is ridiculous; the claim Etheryte denies is a simple restatement of the Lindy effect. For our two objects of ages 5 and 3 years, the "new" claim would tell us the following three things:
1': The expected future lifespan of the first thing is f(5) years.
2': The expected future lifespan of the second thing is f(3) years.
3': f(3) is less than f(5).
But 1' is exactly the same claim as 1, 2' is exactly the same claim as 2, and 3' is exactly the same claim as 3. No claim has been negated, only repeated.
