That's an amazing vision. Soylent shows little to no understanding of the actual problems of food security. There doesn't appear to be any research into the causes of food scarcity, or who is affected by food scarcity, or what a sensible solution would be.
Soylent glop doesn't seem to do anything to increase local independence. Where food could be grown and sold locally now people are importing a bunch of stuff from elsewhere.

How much Soylent does this child need? (http://pinterest.com/pin/278519558175219781/)
How do you get Soylent to the Democratic Republic of Congo?
What do you do when people don't have clean water?
Soylent have made a strong link between food waste and world hunger. They claim that waste here causes hunger there. That's clearly, blatantly, wrong.
I'm all for big ideas and thinking big, but so far this is either a cynical scam or brutally ignorant.
