I remember when I turned 40 I had a similar feeling; it's just still incredible young, especially for such a creative man like John was. The world could have expected so much more from John, but 6 shots distroyed every hope, which is sad enough.
It's true that there is no actual artist/singer who can be compared with John. No doubt that he would have loved to communicate through internet. Of course, this is only speculations, but knowing John...
