Why Moore’s Law does not apply to Digital Photography

Why Moore’s Law does not apply to Digital Photography:

So why do I say that we are near the limit?  The diffraction limit of our lenses is larger than the pixel size on some sensors.  This means that the resolution of some current cameras is limited by the diffraction limit of the lens rather than the pixel size on the chip.  This means that cramming more, smaller pixels on the chip will not result in a higher resolution image when you make a print.
