You are describing the current status. That is not where the doubt is. The article worries about the future and how trends will change. As mentioned in the article what "a real watch" means changed a couple of times and it could change in the future. I'm sure the very ornate gold pocket watch wearer of decades ago sneered at those ridiculous little simple looking things that went on the wrist.
I wear a mechanical watch because it looks nice and doesn't need firmware updates or charging. I need another device to plug in like another hole in my head. But it is nice to know what time it is without pulling out your phone and drawing a lot of attention.
