How absurd. What I have done is done. It does not live. I and someone else or even no one at all might remember it. It might even have been recorded but It was something contingent that someone alive did and completed in the past. It does not live. Those moments no longer exist in reallity.
The information of YOU stays there.

“Those moments no longer exist in reality.”
According to most modern physics “reality”—at least the folk understanding of it—does not exist at all.
So—time traveling is just traveling from one space/time “reality” that does not exist to another space/time “reality” that does not exist.
Let me explain. You are hungry. There is a great dinner sitting at the dinner table across the room and you are ready to go there and eat it.
Problem: Your brain “filter” just stopped working. Instead of seeing and smelling the food you just got to see everything there is—billions and billions of sub atomic waves/particles now lie between you and dinner.
You are so confused you have no idea where dinner went.
What is “reality”—the billions of waves/particles or that dinner?
