1. The “Dark Breakfast Abyss” as a geometric idea
The discussion is built around a simplex that maps egg‑, milk‑, and flour‑based recipes onto a triangle. Users joke that the empty corner of that triangle is a forbidden “dark breakfast” region.
“The concept of a ‘Dark Breakfast Abyss’ in the Breakfast Simplex is hilarious” – ai‑christianson
“The Breakfast Simplex is a space of recipes parameterized by {egg, milk, flour} ratios, normalized onto a simplex.” – DonHopkins
2. Debating what belongs in the triangle (and what doesn’t)
Many commenters argue that the original chart is too narrow, insisting that foods like French toast, bacon, potatoes, or even whole‑meal breads should be added as extra dimensions.
“I feel like there's a lot of unexplored area in the carb‑soaked‑in‑egg category that French Toast fits into.” – noduerme
“I feel like excluding French toast is a serious faux pas here!” – pbnjay
3. Technical analogies and the “vector‑space” framing
The conversation frequently references barycentric coordinates, simplicial complexes, and even embedded constraint graphics to justify the breakfast model, drawing parallels to 3D modeling and language‑model embeddings.
“Simplicial complexes are useful UI primitives.” – DonHopkins
“The same formulation applies to interpolating vector drawings, mesh blending, facial animation, pose spaces, and other example‑based interfaces where states are meaningful and compatibility matters.” – DonHopkins
4. Cultural breadth and critique of U.S. bias
Users bring in international dishes (egg‑paratha, Sri Lankan hoppers, Malaysian roti telur) and point out that the original chart is heavily U.S.‑centric, missing many global breakfast staples.
“In Malaysia, a common breakfast is roti telur + teh tarik which is close to the dark breakfast region.” – muzani
“Egg paratha is a common Indian dish.” – jnaina
“What it's missing is fish, fruit, preserved meats… It's very culturally biased to typical North American breakfast choices.” – bregma
