By "very young", I'm talking about industry that is still figuring out the right direction. Monoplanes made biplanes obsolete, no matter how perfectly the biplane's wing was designed. That kind of dramatic and rapid change tends to happen during the infancy of an industry. See the early shifts from vacuum tubes to semiconductors, from expertly-crafted BJT to crude CMOS, or the rapid march of good-enough architectures in the latest process node clobbering beautiful architectures in older nodes. As the industry has matured and course has stabilized, perfecting the design has grown in importance.
