Whenever I hear anyone talk about Soylent as a utilitarian product made for boring people it always makes me think of the Volkswagen Beetle. Everyone initially thought they were utilitarian cars and only boring people should buy them, until they realized that artists and trendsetters were buying them because a vast majority of people don't use their cars as their main source of artistic expression. There are a lot of people that don't use what they eat as their main artistic expression.
