Arguing over the metaphor isn't useful. This is school-level mathematics. The 'wrong' answer isn't a different optimization of cost, strength, weight and endurance, which Boeing might consider. It's an arithmetic or procedural error giving an incorrect result. There's great value in understanding the method, discussing ways to make errors and so on — but I think it's nonsense to suggest this has anything to do with race.
