If you ever want to extend the analogy to include the perspective of the water here's one to read:
"Over the last few years I've regularly been cornered by nervous publishers or broadcasters or journalists or film makers and asked about how I think computers will affect their various industries. For a long time most of them were desperately hoping for an answer that translated roughly into 'not very much'. ('People like the smell of books, they like popcorn, they like to see programmes at exactly the same moment as their neighbours, they like at least to have lots of articles that they've no interest in reading', etc.) But it's a hard question to answer because it's based on a faulty model. It's like trying to explain to the Amazon River, the Mississippi, the Congo and the Nile how the coming of the Atlantic Ocean will affect them. The first thing to understand is that river rules will no longer apply."
Since you're currently holding a magazine, let's think about what might happen when magazine publishing is no longer a river in its own right..
I've had that happen before. I wrote a somewhat long piano piece that I was unusually impressed with myself for.
I later learned (luckily before I published it anywhere) that it was in fact a melody from a (somewhat well-known) friend's song I had heard some years before, perhaps only 2-3 times, but somehow it remained intact in my head.
Thanks for letting me know. I updated the post to give credit.
