Many of the flaws that the hubless design suffers from might very well be mitigated through further development

Sure, additional refinement could make hubless wheels a reasonable reality. I’ll reiterate one of my original points: all engineering advancements that would make a better hubless wheel would also improve the already great hubbed wheel. Even if we could ignore the complexities of going hubless, the radially supported wheel will be stronger, lighter, simpler, less expensive, more aerodynamic, more repairable.

I might be getting a bit esoteric here, but the same conversations come up in software engineering. “Advances in computing will make Ruby more performant.” Sure, but those advances will be multiplicative in already-performant languages such as C, C++, and Go, whereas they will be fractional in Ruby.
