AI researchers debate whether mind uploading preserves the self

On September 24, AI practitioners on X debated whether a mind upload would still be "you." dioscuri, echoed by Yacine, argued that the self is a pattern that can be multiply instantiated, so uploading preserves identity, and that positing a special extra fact beyond functional and physical properties is implausible. ZyMazza countered that copies are not each other: one's existence does not extend the other's life.

Confirmed

dioscuri/Yacine's core argument: the self is a multiply instantiable pattern with no "extra fact" of identity; dioscuri cited the Back to the Future Marty McFly example to argue one individual can exist in multiple simultaneous instances.
ZyMazza's rebuttal: the two copies are not each other—when one dies the other lives on unaffected, so one does not prolong the other's life.
Bystanders invoked the teleporter paradox: even with perfect data transfer, the copy's conviction of being "you" does not guarantee the original's continuation.
In his summary, dioscuri adopted a Parfitian stance: personal identity has no determinate answer, only cross-instance similarity; he recommended Dynomight's essay "Reasons after nonpersons."

Why it matters

The debate touches the philosophical foundation of AI consciousness, digital immortality, and uploading: if the self is just a pattern, uploading is continuation; otherwise it is mere copying. The Parfitian conclusion offers a framework that sidesteps the binary, one reason the AI community keeps revisiting this classic problem.
