grandfather gizmo

when the government allows people who doesn’t have up-to-date technology yet to see other people’s messages to put them against each other

The grandfather gizmo has been around since smartphones was present and it has caused more societal problems because of it.

The Grandfather Effect

An term made by me at 3 am looking at minutephysics video about the grandfather "paradox"

The Grandfather Paradox is when you go back in time and kill your grandfather but since your grandpa is dead, you cant go back in time since.. u know... you dont exist. But since you dont exist your grandpa exists which means YOU exist but then you go back in time and kill your grandpa, and it keeps going on forever.

But in minutephysics video he talks about how it´s NOT an paradox (cant have links sorry)

Me: Have you heard of The Grandfather Effect?

Friend: No. What´s that?

Me: The definition is: If an action makes that action impossible, that action is both possible, and impossible. - Me 2020, it is kinda like Schrödinger's cat.

Friend: Ok, i understand now.
