This sort of reminds me of those single powder or whatever meals they were awhile back - for those that need to eat but take no pleasure or dedicate no time.
For me, cooking (prep and cleanup included) is about enjoying the process, understanding what I am making and taking time doing it.
If I want quick, sure there are options around.
Cooking for me is relaxation and time away not thinking about tech and the like.
Soylent?
Strangely based on the movie Soylent green
