Good points. The lab-grown aspect definitely colors my image of Soylent negatively. While I don't really mind whether my food comes from a lab or not, I do think food is inherently 'better' when it's created by combining and altering regular food (for Pop-Tarts, it's wheat / corn) versus starting from mostly boxes of powder. Whether it's actually safer, I don't know, but the perceived safety of a Pop-Tart is definitely higher. For me, it's also the diversity aspect: Soylent tries to include as much good and nutritional ingredients as possible, whereas most food does not (or not to such a degree as a Pop-Tart). The diverse combination of ingredients that Soylent has is likely not as understood as a combination of wheats, corns, vitamins, colorings, preservatives etcetera that most of my food consists of. To put it bluntly, it's a bit scary because it's new. I wouldn't want to test a new type of parachute for the same reason. Give me the tried and tested when my health is at stake.
