Viewing Soylent as a replacement for every single meal would be scary and potentially dangerous. However, I think it would be difficult to compare the nutritional value of a meal comprised of McDonalds and Coke to a meal of Soylent and to find the Soylent wanting or not superior in every way.

Personally I'm excited to get my month's supply of Soylent, because at the very least I know it won't kill me, and at the very best I'll have some more free time and extra pocket money to spend with good friends or a good book.
