问HN：为什么软件开发人员不制作医疗设备？
随着大型语言模型（LLM）的发展，软件开发逐渐成为一种商品，我不禁想知道为什么更多的软件开发者不转向医疗设备的构建，以使他们的职业生涯更加稳固。以下是我特别选择医疗设备的原因。
1. 自然护城河
由于人体硬件在其最基本的部分几乎是不可变的，你不必担心某些LLM的炒作周期会取代你。一旦你建立了产品并获得FDA或当地的认证，你就可以安心了。与优步摧毁出租车牌照业务不同，医疗行业是一个庞然大物——没有科技初创公司敢于绕过所有的法规和把关。
2. 监管护城河
我所说的医疗设备需要大约50,000到200,000美元的FDA认证费用——这个金额足够小型企业承担，但又足够高以阻止一些低端竞争者和中国产品倾销者。这也让你能够避开那些大型成熟的医疗企业，因为这个市场细分对他们来说太小，他们不会在意，但又足够大，让你每年能获得1000万到1500万美元的收入。
医疗设备制造规避了软件开发的两个致命缺陷：缺乏护城河和几乎没有变化的硬件利润率。LLM公司不关心版权、知识产权或更广泛经济的健康——但它们无法与医疗行业直接竞争，因此你根本不必担心它们。

As software development becomes a commodity thanks to LLM, I wonder why more software developers don't switch to building medical devices to make their careers more secure. Here's why I picked medical devices in particular.<p>1. Natural Moat<p>Since human body hardware is more or less immutable in its most essential parts, you don't have to worry about some LLM hype cycle replacing you. Once you build the product and clear FDA or local certifications, you're set. Unlike Uber destroying the taxi medallion business, healthcare is a beast — no tech startup dares to bypass all the regulations and gatekeeping.<p>2. Regulatory Moat<p>The medical devices I'm talking about require around $50K–$200K for FDA clearance — low enough that any small business can manage it, but high enough to discourage bottom-feeders and Chinese product dumpers. It also lets you avoid the big established healthcare corporations, because this market segment is too small for them to care about, yet large enough for you to pull in $10M–$15M a year in revenue.<p>Medical device manufacturing sidesteps the two fatal flaws of software development: the lack of a moat and static, almost never-changing hardware margins. LLM companies don't care about copyright, IP, or the health of the broader economy — but they can't go head-to-head with the healthcare industry, so you don't have to worry about them at all.
