A Mexican Physicist solved a 2,000-year old problem that will lead to cheaper, sharper lenses

There's no way this leads to cheaper lenses, in the short term at least, despite any cost saving manufacturers make. Sharper images and fewer moving parts? Charge the same, or more.

As an ameature photographer, I'm not sure how I feel about it. Of course, you want your photos to be as sharp as possible, but softer edges can sometimes make the photo. And as you adapt to the limitations and imperfections of your equipment, your composition improves too.
