'ramen profitable' and it's derivatives should be taken as a cutesy fluffy marketing term and nothing more (like most startups were never actually started in a garage).
No one should be living literally off Ramen noodles and cereal. It's incredibly bad for your health and a total lack of investment in your body and your brain.
I'm not saying YC's small funding encourages this, but nevertheless we should not be encouraging the promotion of this concept.
