If you live in a country which adheres to standards of food safety and has regulatory bodies to protect and promote public health then I disagree. You entrust those bodies and the qualified individuals within them because they ensure what you purchase is what it says it is. Soylent has not reached this level of evaluation.

If Soylent works completely as advertised yes you gain time. Should it lead to any kind of health problems it's more than likely you lose time.
