The creator of Soylent has a different, much more ambitious goal than just replace food. I think he's trying to make a substance that will be much better and more efficient than 'regular' food. Giving the body not just what it needs but what it could use to make the most out of itself. Check out Tim Feriss' test of the beta Soylent. A more neutral point of view to say the least. Interesting as this is, it's very arrogant to assume we can know what the body needs and reverse engineer from that. It scarily reminds me of the birth defects caused by Softenon in the sixties, when we found out that different turning molecules can have a radical difference on the birth of babies. I really hope it succeeds but they might be treading on dangerous grounds.replacement
