【思想聚焦】"优秀产品难以被迭代"理念引发行业深思

著名投资人纳瓦尔近日在跨学科研讨中指出，优秀产品与优秀理论具有相同特质——它们都"难以被变异"。这一观点源自哲学家大卫·多伊奇的认识论体系，现已被延伸应用于产品创新领域。

以iPhone为例，尽管历经16代更迭，其核心设计理念始终围绕全面屏、多点触控、内置电池等要素展开。这种被称为"柏拉图式理想形态"的设计，正如同圣埃克苏佩里所言"完美不在于无可增，而在于无可减"的机翼设计，形成了难以突破的经典范式。

该现象在多个行业均有体现：传统燃油发动机历经百年演进仍保持基本结构，直至电动车技术突破才实现范式转移；现代汽车外观日趋同质化，实则是风洞测试下空气动力学最优解的必然结果。这些案例印证了"优秀设计具有内在约束性"的规律。

专家指出，这种"难以变异"特性恰恰标志着产品达到成熟阶段。就像航天器通往火星的设计方案，在技术突破前将保持相对稳定。与此同时，知识传播本身也呈现类似特征——优质内容具有分形特质，不同认知层级的受众都能从中获得相应启发。

这一跨学科理论为创新领域提供了新视角：真正的突破性设计往往在约束中诞生，而经得起时间考验的产品，终将在迭代中显现其不可替代的价值内核。

优质产品难以被篡改
纳瓦尔：我认为阅读多伊奇跨学科的著作非常有用。即使当他谈论模因和模因理论时——虽然理论源自进化论，却能直接贯通认识论、猜想与批判性思维。
其影响远超出他对财富的定义：即你能实现的物理转变集合。这个定义同时涵盖资本与知识，并清晰表明知识是更重要的组成部分。这些思想既能引入商业领域，也能应用于日常生活，既适用于国家财富积累，也适用于个人财富增长。

这些理论部件彼此紧密交织。
他提出"优质解释难以被篡改"。当你回溯某个优质解释时，你会感叹："事情怎么可能不是这样？这是唯一行得通的解释方式。"
所有理论部件严丝合缝地相互制约，最终涌现出意想不到的特性、复杂性或结果——形成能完美解释一切的终极阐述。

这个原理不仅适用于理论解释，同样适用于产品开发。
优质产品难以被篡改。
以iPhone为例：这款光滑完美如珠宝的设备。其基本形态自初代以来并未发生本质改变——始终围绕单屏幕、多点触控、内置电池、便携口袋设计、流畅手持体验展开，本质上创造了真正个人化便携电脑的柏拉图式理想形态。

因此这个产品难以被篡改。苹果及其竞争对手历经16代iPhone尝试改动，都未能实现本质性变革。他们可以升级组件、提升底层性能，但产品形态本质上已难以改动——因为最初就确立了正确设计。
圣埃克苏佩里有句名言："完美不在于无可增添，而在于无可删减"。
飞机机翼正是难以篡改的典范。

我相信当我们确定前往火星的航天器设计方案后，无论是整体架构还是具体细节，在相当长时间内都将难以改动，直到突破性技术出现。
内燃机的基本设计曾经难以改动，直到高性能电池技术成熟催生电动汽车。而现在电动汽车的设计也趋于固定。

事实上已有设计师抱怨，现代社会中的产品外观正趋于同质化。这是社交媒体的影响吗？原因何在？
至少在汽车领域，所有车型都经过风洞测试设计，因为这是最优效率方案。它们呈现流线型外观的根本原因，是要找到空气阻力最小的形态。最终所有设计殊途同归，因为任何改动都会牺牲效率。

优秀作家的作品具有高度凝练性与互联性，本质上是分形结构。你总能在适合自己认知水平的层面汲取知识。
无需强求全盘理解——这正是学习的本质。初读理解20%，重温获得25%，配合播客学习提升到28%，借助智能工具深入钻研某个环节，最终达到31%。
所有知识都是作者与观察者之间的双向交流，需要双方认知水平同频共振。当你准备好接收不同知识模块时，自会获得相应内容。只要具备基础语言能力，无论处于何种认知层级，总能从中获得启迪。

Good Products Are Hard to Vary
Naval: I think reading Deutsch across all the different disciplines is very useful. Even when he talks about memes and meme theory—that comes from evolution, but crosses over straight into epistemology, conjecture, and criticism.
And it reaches far beyond his definition of wealth: the set of physical transformations that you can effect. That takes into account both capital and knowledge, and it clearly shows that knowledge is a bigger component. And then that can be brought into business and applied into your everyday life. It can apply to the wealth of nations and it can apply to the wealth of individuals.
So there are a lot of parts that interconnect together.
He says that good explanations are hard to vary. So when you look back on a good explanation, you say, “Well, how could it have been otherwise? This is the only way this thing could have worked.”
All these different parts fit together and constrain each other in such a way that there’s now some emergent property or some complexity or some outcome that you didn’t expect—some explanation that neatly explains everything.
That doesn’t just apply to good explanations. It applies to product development.
Good products are hard to vary.
Go look at the iPhone: this smooth, perfect, beautiful jewel. The form factor hasn’t really changed that much since the original one. It’s all around the single screen, the multi-touch, embedding the battery, making it fit into your pocket, making it smooth and sliding in your hand—essentially creating the Platonic ideal of the truly personal, pocketable computer.
So that product is hard to vary. Both Apple and its competitors have tried to vary it across 16 generations of iPhone and they haven’t been able to materially vary it. They’ve been able to improve the components and improve some of the underlying capabilities; but materially, the form factor is hard to vary. They designed the right thing.
There’s a famous saying, I think from Antoine de Saint-Exupéry, where he says the airplane wing is perfect “not because there’s nothing left to add, but because there’s nothing left to take away.”
That airplane wing is hard to vary.
When we figure out the proper design of the spacecraft to get to Mars, I will bet you that both at a high level and in the details for quite a long time, that thing will be hard to vary until there’s some breakthrough technology.
The basic internal combustion engine design was hard to vary until we got batteries good enough and then we created the electric car. And now the electric car is hard to vary.
In fact, there’s a complaint now among some designers that in modern society, products and objects are starting to look all the same. Is that because of Instagram? Why is that?
Well, at least in the car case, they all look like they’ve been through a wind tunnel design because that is the most efficient design. The reason they all look swoopy and streamlined is because they’re all going through a wind tunnel and they’re trying to find the thing that cuts through the air with minimal resistance. And so they do all end up looking the same because that design is hard to vary without losing efficiency.
Good writers write with such high density and interconnectedness that their works are fractal in nature. You will meet the knowledge at the level at which you are ready to receive it.
You don’t have to understand it all. This is the nature of learning. You read it, you got 20% of it. Then you go back through it, you got 25% of it. You listen to one of Brett Hall’s podcasts alongside it, now you got 28% of it. Now you go to Grok or ChatGPT, you ask it some questions, you dig in on some part, now you got 31% of it.
All knowledge is a communication between the author and the observer or the reader, and you both have to be at a certain level to absorb it. When you’re ready to receive different pieces, you will receive different pieces, but you’ll always get something out of it no matter what level you’re at, as long as you can even just communicate and read the language.
