Sometimes, a writer's job only involves contemplating the story. That's not the same as writing. It can happen between sentences, or it might take the form of long stretches when wistfulness clouds the eyes. Generally, my hearing stops working while my story is swirling around in my head.
This could change with technology, when computers gain the ability to read our thoughts. I've read that a form of this type of virtual reality technology is being developed. In my Luddite-lite worldview, my warning sirens go into Category 5 hurricane mode (BTW, 5 is the most severe hurricane). If thinking a story becomes a way to write a story, would a computer capture every thought and plot line that my brain thinks? How would I revise such a conglomeration? My thoughts go in hundreds of directions before I write them, so much so that the physical act of actually writing a coherent string of words is the thing that makes them coherent.
Writers have been using dictation to write stories for a while. I tried this once several years ago using speech-to-text software, but it wasn't sophisticated enough to understand all my words and the flow of my speech pattern, so I forgot about it. However, a case can be made that speech-to-text could be a productive option for many and make a writer's wordcount soar.
There may come a time when the way we write doesn't involve "writing" anymore. Consumer pressure for more words and stories, faster and faster, to make a living and satisfy audiences could send the keyboard into obsolescence. Then we may find ourselves waxing nostalgically about the days when we used a laptop. Our Chromebooks and MacBooks would fall in with the dinosaurs and the rotatory telephone. (Somewhat ironically, the speech-to-text software marketed to writers is called Dragon.) Or, it could be that this development will peter out like other changes in technology. Hardcopy vs. ebook, anyone? I also know writers who still use pen and paper.
Nonetheless, if you have a rotatory phone because it's cool, rock on! And if your vinyl collection is lovingly intact, you are my hero! Maybe I'll just stay retro and write the old fashioned way, one keystroke at a time.
