Really? Very strange logic? I experience future versions of myself in the future, and present version(s) of myself in the present. That seems normal. You say, "they [future versions] are also you." But your tense is wrong. Don't you mean... "will be also you"?

The fact that the software copy of me is in my present time frame and yet is obviously separate from me seems to force the conclusion that I am not it, generally, in all time frames. This does not fill me with confidence that I will live on in any sense in this software copy once my present conscious experience is snuffed out.

Why does the time "you" exist matter? Whether another version of you exists in the present time or 10 seconds in the future, it's still "you".
