I've always said that teleporters are just suicide machines that sometimes spit a clone out somewhere else.

It wouldn't be you, it would just be another person with the same memories that you had up until the point the copy was made.

When you transfer a file, for example, all you are really doing is sending a message telling the other machine what bits the file is made up of, and then that other machines creates a file that is just like the original - a copy, while the original still remains in the first machine. Nothing is even actually transferred.

If we apply this logic to consciousness, then to "transfer" your brain to a machine you will have to make a copy, which exist simultaneously with the original you. At that point in time, there will be two different instances of "you"; and in fact, from that point forward, the two instances will begin to create different memories and experience different things, thereby becoming two different identities.

The first line passes the argument by reference, ie, the object itself.

The second line passes the object by value, ie, a copy.
