Yerp. Even a perfect duplicate of you a la a Star Trek transporter malfunction wouldn't really be YOU. At least not the you that you care about. (Speaking of movies, I'm suddenly reminded of The Prestige...again.)
Any replica of a person would offer no more immortality than entering cultural mythology. 🙄
Follow-up question, this time a potential head-scratcher: Star Trek transporters convert a person into energy and then reconstruct them somewhere else. Their consciousness remains intact during this process. What of their soul?
