The efficiency issues of DePIN (Decentralized Physical Infrastructure) are worth serious consideration. Rather than being a technological advancement, it is more like an experiment in incentive mechanisms — when we reward dispersed node operators around the world with tokens, coordination costs, redundancy waste, and operational complexity all increase. In contrast, centralized infrastructure has natural advantages in economies of scale and technological standardization. This raises a fundamental question: what is the true value proposition of DePIN? Is it decentralization for its own sake, or can it truly offer advantages that centralized solutions cannot match in specific scenarios? Perhaps we need to abandon the obsession that "DePIN will inevitably succeed" and instead consider what kinds of infrastructure services genuinely benefit from decentralized governance.
