History has a funny way of repeating itself. The skeptics dismissing blockchain and crypto today aren't entirely different from 19th-century critics declaring aviation impossible—both eras feature smart people making logical arguments against technologies that later transformed the world. The Wright brothers faced similar certainty that heavier-than-air machines violated physics. Today's doubters cite regulatory hurdles, scalability challenges, and volatility concerns. Yet each "impossible" barrier keeps crumbling. The difference isn't the technology—it's whether you're watching or building.
