That sounds sufficiently different from me that it won't be me.

If I'm going to identify with some future entity that's very different from me it might as well be something newly arisen, not something having a copy of some of my memories somewhere.

I guess those archived memories are the ultimate time capsule. If that becomes common they'll ultimately go the way of all archives.
