Artificial intelligence is bringing the dead back to 'life' -- but should it?

What if you could talk to a digital facsimile of a deceased loved one? Would you really be talking to them? Would you even want to? In recent years, technology has been employed to resurrect the dead, mostly in the form of departed celebrities. Carrie Fisher was digitally rendered in order to reprise her role as Princess Leia in the latest "Star Wars" film.
