Mmm, storytelling is not dying. But you're right, there are too many voices many without the talent to write. Nearly everyone feels they can write. That they are the next Hemmingway, Steinbeck or King ... sadly it's not true. Those people would be better off writing a journal or possibly a blog, or writing for themselves.
There are still writers out there who put in the hours, effort, research and editing required. We do it for nothing, only asking for a like or a comment on our work.
We should be grateful not everyone feels they can paint, or sculpt ... can you imagine?
