I'm trying to figure out how a minimalist style society would work. Its secretive founders have been planning this since the 19th century, hiding in universities, influencing the young to attempt to develop the desired technologies. They hope to wait for the natural collapse of complex global society and swoop in when their time has come. Their ultimate goal is to create a civilization which could last 100000 years.
In order to do this they plan to optimize certain aspects of the human condition and transcend certain memes and schema about how basic human activities must work.
They want to transcend the schema surrounding entertainment, they want to replace it with soma (pleasure chemicals), wireheading (stimulating the brain for preferred mental states) and emotional discipline methods (e.g meditation). They want to transcend the schema where food = plants/fungi/animals. Just as vehicles use fuel to continue existing, so can humans use "body fuel" to sustain their existence.
There needs to be some way to turn raw materials into body fuel which is as cheap or cheaper than agricultural methods.
