My first thought whenever I see soylent is that we have studies proving that we can't replace breast milk with baby formula. Some of that is due to immune system being passed on to the infant, but we haven't yet mastered the nutritional content of real food to the point where we can confidently say it's safe to eat Soylent or another similar product regularly.
It takes me back to the whole issue with processed dog foods -- kibble, while even the most expensive brands claim to be "nutritionally complete", miss the fact that dogs cannot process/absorb the many nutrients within (and why their waste is... more than a nuisance). Eg, calcium added to dog food is nearly worthless, while calcium from eating raw bones is readily absorbed by their bodies. Same with many other vitamins and minerals.
We have a lot of work ahead of us in this sector. It's good that someone is trying, though.
