The sheer convenience of smart phones mean that most of us are equipped to be photographers. Long gone are the days of needing a high end camera to take the memorable image. For years some people have been under the misapprehension that a great camera and great lens will produce the great photograph. On that basis the super wealthy would corner the market. These days it's more important to get the shot and not fret over the quality than no image at all. It's really as simple as that. Megapixels might do it for the pixel buff, but for mine it's the image that counts rather than the equipment. A smart phone won't necessarily deliver smart photographs but it's mobile for sure and importantly, unobtrusive. A pro camera can be a burden in many situations while the mobile phone is definitely a much smarter thing.
It's horses for courses. In an ideal world shoot on the biggest and best you can afford. If all else fails get there by the means at your disposal. I liken it to flying business class, or first class for that matter versus cattle class. It may not be as pleasant but you arrive only seconds after those who decide to stump up the big bucks. And think of what you saved and can spend now that you've arrived. A new camera or smart phone perhaps with plenty of cash to spare for more equipment and wider travels.
In the end it's the idea that matters and what sells. And even the smart phone requires a degree of smarts to help it achieve the promise of its name. But small pixels or not, it definitely delivers remarkable bang for the buck.
