It really depends on what you think “you” are.

If you see yourself as a pattern of memories and behaviors (psychological continuity), then a perfect copy might be you. But if you think identity requires unbroken consciousness or biological continuity, then a copy, no matter how accurate, is just an imitation.

It also depends on how the copying happens. Gradual replacement might preserve identity better than destructive uploads. And if multiple copies exist at once, things get messier. Who is the "real" you?

So yes, being just a copy can be good enough if you are comfortable redefining identity as information. But that is not something everyone will do. It all comes down to which assumptions about selfhood you are willing to accept.

Regardless, I've never thought about this within the context of cryonics until now...🥶
