End of postal service

There is talk of postal service ending sat delivery right now. However, could the postal service itself be gone? I believe that will come. In fact, many will live to see it no more. It will join eight track tape, floppy disks and VHS as one more technology we no longer use. Physical deliver of mail will seem quaint to people who live in the days to come. John Titor said that there was still mail delivery in 2036, but that was on his timeline, not ours.
