Terminator 2 the ending you never saw

Terminator 2 I bet you never knew there was an alternate ending to the movie where everything is very different.
And although it seems that we already know all the secrets behind Terminator 2 starring Arnold Schwarzenegger and Linda Hamilton, there is a secret that – to date – not everyone has in mind: a deleted scene that completely changed the future of the saga.
In the scene, Sarah Connor is seen watching her son (now an adult) play with her granddaughter. This is how she decides to tell how the Day of Judgment came, and never was, and no one but her and John knew about the dark fate of humanity. This means that the iconic battle between humans and machines never happened.

Terminator 2: Judgment Day, also known as The Exterminator 2is a 1991 film directed by James Cameron and starring Arnold Schwarzenegger, Edward Furlong, Linda Hamilton and Robert Patrick.
He won four Academy Awards (1992) for Better visual effects, Best makeup, Better sound and Best Sound Editing.
Synopsis
It’s been 10 long years since the first Terminator tried to kill Sarah Connor, the mother of the one who would be the liberator of the future. Skynet has created a new kind of Terminator and sends him back to the past to kill the now teenage John Connor.
But from the future, John Connor himself has sent a replica of the old Terminator T-800 to protect himself. The problem is that the 10-year-old John Connor does not believe in the future and much less in robots but when he comes face to face with the powerful and indestructible Terminator T-1000, he radically changes his mind and discovers that everything his mother told him about a future dominated by machines was true.
So John and the T-800 are going to rescue Sarah so that between the three of them they end the threat of Skynet by going directly to the scientist who created it: Dr. Miles Bennett Dyson.
