Excluding the tedious and complex experimental arguments, here's the conclusion.
The copying of memory is not the copying of memories but the cutting of the soul!
And this cutting doesn't just remove a corner of the soul; it shaves off an entire layer of the soul's thickness.
To illustrate, if the soul is a sheet of rice paper, memories are the paintings on the paper. The technology for copying or transferring memories is akin to cutting the paper with scissors.
It's not a vertical cut but a horizontal slice through the middle.
Thus, although the painting is "transferred" intact to a new medium, the original paper irreversibly thins.
The colors on the paper fade and blur; those fading memories and blurred images are not mere forgetfulness but a deeper, soul-level depletion.
It's permanently irreversible, impossible to glue back together.
