(For those who don’t know and do care, the impossible trinity, also known as the trilemma, is a concept in international economics that my brain managed to retain from college.)
EDIT: This guy claims to have solved the problem by creating the ultimate nutritional shake, which he dubs “Soylent.” Yeah, I find that a bit off-putting. I have trouble understanding how he saves time with this, given that he needs to weigh the ingredients with a gram scale every time he mixes the drink, but I guess that still takes less time than most cooked meals. If it could be made widely available with the proportions just right, it would be very convenient indeed.
