We don't have any rudiments of teleportation or replication.

Certainly not as Star Trek depicts such technologies, no. But, then again, if FTL travel is ever devised, assuming some subversion of Einsteinian principles, do you really think it's going to involve dilithium crystals?

Given my belief that a person will, eventually, no longer need to be tied to a specific physical body, teleportation would be reduced to sending a packet of information comprising the vital data which make up a person's unique intelligence/persona from Pt. A to Pt. B, whereupon it can, if needed, be installed into a physical shell constructed at the remote location. And, with nanoassemblers capable of those kinds of feats, the concept of replication is already rendered obsolete.
