I think the rough part of that analogy is that steel is at a different stage in its lifecycle as a product. Some innovation, to be sure, but nothing like this pace. Here, iteration speed is paramount. Perhaps SpaceX should move somewhat more slowly and focus more on safety, but I hope that people keep in mind that the only way to be perfectly safe is to do nothing with any risk, which in this case translates to making no real progress on rocketry. That comes with species-level risks. And if you double the amount of stuff done for each iteration, it might increase production time by much more than double, or potentially make some of the more difficult things impossible, as focus and momentum is lost, and mental state decays more between iterations.
