>To start with, a large portion of the photography process has been removed — and not simply a technical part, but a creative part. There’s a reason focus is called focus and not something like “optical optimum” or “sharpness.” Focus is about making a decision as a photographer about what you’re taking a picture of. It’s clear that Ng is not of the same opinion: he describes focusing as “a chore,” and believes removing it simplifies the process.

You really seemed to miss the point here. The Lytro camera captures all possible focus settings, allowing the photographer to choose one later...or combine multiple settings together in a single image. This isn't the machine taking over the photographer's job, it's the machine increasing the choices available to the photographer. Similarly, you might not like images which have been heavily dodged/burned, but it certainly was a victory for artists when that technique was developed, allowing them to choose differing levels of exposure in the same image.
