It's a difficult problem, but food just takes too much of people's time. Something like a personalized service that brings you food according to your own nutritional schedule would be nice.
I feel that a lot of people receive a lot of joy from selecting good food from a variety of options. I think with the immense popularity of websites/apps like Yelp, people are even more picky eaters than ever before. I think this makes a personalized food service incredibly difficult to appease a wide net of people and tastes while considering things like costs and logistics.
Of course the existence and popularity of something like Soylent goes against my assumptions. I imagine there are just people who value their time over enjoyment from food, as well as people who feel the opposite.
I feel the opposite. There's no shortage of startups trying to serve you every kind of food on the planet quickly and cheaply, but more often than not the enjoyment is in actually going out and spending some time at the restaurant or preparing a nice dish on your own
