这些巨头通过消除非标服务带来的不确定性，降低消费者的心理成本，从而获得更强的品牌议价权。宠物行业早期更像是产品创新驱动市场，小品牌可以靠单点爆品快速成长；但随着行业成熟，竞争正在逐渐转向系统能力竞争，包括供应链稳定性、合规能力、研发周期、品牌信任积累以及长期服务能力。，这一点在同城约会中也有详细论述

But what if it’s not fine? Even back in 1996, before a single component of the ISS was launched into orbit, NASA foresaw the possibility of an even worse worst-case scenario: an uncontrolled reentry. The crux of this scenario involves multiple systems failing in an improbable but not completely impossible cascade. Cabin depressurization could damage the avionics. The electrical power system could go offline, along with thermal control and data handling. Without these, systems controlling coolant and even propellant could break down. Unmoored, the ISS would edge slowly toward Earth, maybe over a year or two, with no way to control where it is headed or where its debris might land. And no, we could not save ourselves by blowing the station up. This would be extremely dangerous and almost certainly create an enormous amount of space trash—which is how we got into this hypothetical mess in the first place.
