What the article does not seem to be aware of is that most Photographic workflow products, such as Aperture and Lightroom, are working in a 32-bit colorspace even if you open an 8-bit JPEG. The reason is simply that to work in RAW consistently, your tools need to be working at a higher bit-depth than the existing RAW images you are trying to use. Some RAW formats are 14 and some 12. High-end Hasseblads are 16. It is not unlikely that future sensors will go beyond 16 bit. Therefore it makes sense to design the workflow around 32-bit processing. Otherwise you are stuck re-architecting your entire workflow. Witness the number of Photoshop filters which only work at 8-bit.
