From: Karri Saarinen, Linear — Read the original
Karri Saarinen is the co-founder and CEO of Linear which made craft a competitive advantage. He is not a theorist. He builds things, ships things, and thinks carefully about how.
Generating Form Is Not the Same as Solving the Problem
“The hard part of design is rarely generating the form. It is understanding the problem well enough to know what and how something should exist at all.”
Most people treat design as a production problem. How fast can you get something on screen. How quickly can you move from idea to interface. The entire AI tooling conversation is built on that assumption, that speed of output is the constraint worth solving. Saarinen says the constraint was never there to begin with. The bottleneck is comprehension, not production. You can generate a hundred screens in the time it used to take to sketch one, and still have no idea what you’re actually building or why. Faster hands do not produce better thinking. They just produce more noise faster.
Context Is Not Background, It Is the Whole Problem
“Context, in his sense, is not a background condition. It is the full set of forces that make a problem what it is: human needs, technical constraints, conflicting requirements, habits, edge cases, and relationships that are easy to miss until you spend time with them.”
Saarinen reaches for Christopher Alexander here, specifically the idea of fit between form and context. The reference matters because Alexander spent his career arguing that bad design is not an aesthetic failure, it is a relational one. A thing fails not because it looks wrong but because it sits wrong inside the forces that surround it. Those forces are invisible until you’ve spent real time with the problem. Edge cases, conflicting needs, habits people can’t articulate. None of that shows up in a prompt. You encounter it slowly, through use and conversation and iteration. AI doesn’t have access to it. Most designers who skip that work don’t either.
Polished Is Not the Same as Good
“You can already see the result in products that look polished, ambitious, and impressive at first glance, but begin to unravel the moment you actually use them.”
This is the thing nobody wants to say out loud because it requires admitting that what you shipped might be beautiful and wrong. The AI design era has produced a particular aesthetic: high fidelity, visually confident, immediately coherent. And hollow. The decisions that make software feel inevitable, that make you forget it’s software at all, come from someone working through a thousand small tensions carefully. That work leaves no visible trace, which makes it easy to skip. The result is products that photograph well and frustrate deeply.
Working Visually Is Thinking, Not Just Producing
“Moving things around, testing relationships, and refining structure is not separate from the thinking. It is part of how clarity emerges.”
There’s a version of efficiency that is actually avoidance. If you skip the slow, tactile process of working through a problem visually, you don’t save the time. You defer the reckoning. Saarinen draws the comparison to writing. The value of writing is not the document. It is what happens to your thinking while you write. You discover what you actually believe by trying to say it precisely. Design works the same way. The act of placing things, adjusting relationships, pushing elements against each other is how you find the real shape of what you’re making. Handing that to a tool doesn’t accelerate your process. It amputates part of it.
AI Can Assist, It Cannot Understand
“AI can still be useful. It can help prototype, explore, and surprise you. But that is different from design.”
The honest use of AI in design is not as a replacement for judgment, it’s as a fast sketch pad. You can use it to generate starting points, to pressure-test directions, to surface options you wouldn’t have reached alone. But the moment you let it make the actual decisions, the ones about what this product is and what it demands from the people who use it, you’ve handed off the part that requires a person. The tool can produce the form. Only you can ensure the fit.
The Bottom Line
The AI moment has made output cheap and comprehension still expensive. Saarinen’s argument is that they were never the same thing, and conflating them produces work that looks finished but isn’t. Design is the long, patient act of understanding what something should be. Everything else is decoration.
