Do you think your sense of identity could exist independently of the physical architecture it currently resides in?

For example, could “you” be downloaded to a computer and run on the computer and feel exactly the same as you do now? Or for that matter, could you be downloaded and feel even remotely similar enough to recognize yourself?

Is there some essence of you that is independent of your body, somehow, that could retain its own consciousness without having a living body to “run on” so-to-speak? Can you think without a brain? Can your “essence” exist independently of matter? Or in any way independent of your body?

Or, are you and your body an artificial duality? Are you, in fact, the same thing, unseparatable? Just an idea or a metaphor, but not something with any reality?
