Interesting article about using software to create "photographs" for advertising and other uses. I am sure that many of the advertisements I have seen in the last few years were made this way.
As a photographer, if the connection to reality is irrelevant to your work—like it is in a lot of advertising, product, and even landscape photography—there is a good chance that a sixteen-year-old in Bangladesh will be able to produce marketable imagery for a fraction of the cost. And he won't need a 40-megapixel Hasselblad or studio full of lights. But if you traffic in non-fiction photography, if your work capitalizes on photography's one distinguishing feature, then a rendering will never replace your work.
