A startup in Seoul's Gangnam district recently laid off five of its developers. The reasoning was simple: an AI had rebuilt, in three days, a web application the team had spent three months completing. "We need people who decide what to build more than we need people who build it," the CEO said.

So while AI codes, designs, and translates, what is left for humans to do? The work of connecting markets to products—in other words, product vision.

A product planner is a translator

It's a mistake to think of a product planner as simply the person who comes up with ideas. A product planner translates the language of the market into the language of the product. They hear the market shouting "I need something like this," and they convert it into "this is the product that solves it."

No matter how brilliant a developer is, that talent means nothing if they don't know what to build. A gifted designer who doesn't know who will use the work produces nothing more than self-satisfaction. Only the person who understands both the market that will pay and how to build the product for it survives.

Deciding how to use the technology is still a human's job

Back in 2016, mastering QuarkXPress—a Mac-only publishing program—took at least six months of study. And today? A few hours with Adobe InDesign, Photoshop, or Illustrator is enough for anyone to produce professional-grade work.

Add 3D printers, AI-driven content generation tools, and automation systems, and the technical barrier to entry has, for all practical purposes, collapsed. This is an era in which you can build a business by drawing on other people's technology—even if you don't understand the technology yourself—as long as you have product vision.

What matters is the ability to judge where the technology should be applied. Holding a hammer is useless if you don't know where to drive the nail. Even when AI handles the coding and the design, "what to build" is ultimately a decision that falls to a person.

The people who close the gap are the ones who make money

Large companies have separate marketing, planning, and development teams, so each can simply do its own job. Solo founders are different. Alone, they have to handle the market research, the product planning, and the marketing too. The most common mistake in this process is the lament: "I built a great product—so why won't it sell?"

The product planner is precisely the person who narrows that gap. They measure the distance between what the market wants and what the technology can do, and they find ways to minimize it. A true product planner has both a talent for market research and an instinct for product development.

Test yourself with three questions

There's a simple way to find out whether you're a real product planner: Can you answer three questions clearly?

First, do you understand what the market wants? You should be able to answer with data, not guesswork. Second, are you convinced that the product you've built is worth paying money for? The test is whether you'd buy it with your own money. Third, do you know specifically where to apply the technology to turn a profit? The point is that you should be able to think about where to use a technology rather than fixating on the technology itself.

If you can answer "yes" to all three, you're a product planner who's ready. If your answer is "well…" or "maybe," then it's time, starting now, to build the planner's way of thinking.

Product vision isn't merely a job skill—it's a survival capacity humans absolutely must cultivate in the age of AI. Leave the technology to AI, and let us become the people who decide what to build with it.
