For public chains, focusing solely on TPS is a very lazy approach, much like how, ten years ago, a bunch of smartphone manufacturers held press conferences bragging about their benchmark scores surpassing Apple's, or how in recent years, many car manufacturers have held press conferences boasting about their range exceeding that of Tesla. However, most of those once high-scoring flagship phones and long-range newcomers have ultimately become industrial waste, discarded in the annals of history. In engineering, technical metrics are the easiest to quantify and achieve. If a manufacturer constantly brags about its technical metrics, it certainly indicates insecurity and incompetence in its real commercial competitive ability. The true competitive edge that stands out is often unquantifiable and even directionally uncertain, requiring more bottomless investment compared to achieving visible technical metrics. You can think of these industrial wastes that have become self-satisfied due to achieving certain technical metrics as small-town test-takers who haven't yet gone to college and have not been beaten down by society (no offense intended). They genuinely believe that memorizing vocabulary and solving equations quickly will lead them to become CEOs and marry beautiful, wealthy partners, thus becoming winners in life. This is also the reason why there are many distorted "king-level" projects in the Ethereum ecosystem and the entire Infra field, driven by VC. Big money only flows toward certain directions, leading to a plethora of performance-oriented projects like Starknet and Scroll attracting a swarm of VCs. After all, when VCs report to LPs on why they invested in these industrial wastes, they can provide a seemingly comprehensive and persuasive report, thus creating a vicious cycle of continuously producing industrial waste.
