      Sends original data vs making a copy of data and sending it.

      In meme context you’d be just making a copy of your consciousness and putting it in a machine. Whatever reason you’re doing it for - escape illness, survive armageddon, nothing changes for you. A copy of you lives on though.

        I mean, just kill the host as soon as the upload is complete. at best you are not conscious during the process and when “you” wake up you are in the cloud. The version of you that awakes gets told that the “transfer” was complete.

      I guess you ask for C++. There Type* can be null while Type& can’t be null. When it gets compiled Type& is compiled (mostly) to the same machinecode as Type*.

      You can pass nullptr in the second example (that is not what OP wrote though, hes second is making a copy).
