I've never been so sad as when I read the New Yorker profile[1] of the creator of Soylent. Most people understand that food can be extremely healthful, and is a crucial part of culture and social bonding.
It's not so much the idea of smoothies or protein shakes or yogurt drinks or whatever (tasty) on-the-go nutrition you choose. It's the mentality around "lifehacking" and my work being too important and all-consuming to partake in the types of life activities that the muggles do.

The average American meal is not a healthy, fulfilling group activity. Soylent is there to replace those meals and free up time and money to more frequently enjoy the other type of meal (or whatever else you might want to do with your time).
