Graphic design moved from bitmap heavy visuals to illustration, SVG-first systems — faster, cleaner, and scalable. But does abstraction slow understanding, and will AI pull us back toward photos?
There was a time when bitmaps ruled everything.
If you wanted richness, realism, emotion, or detail, you reached for a photo, a texture, a gradient, a noisy overlay and you saved it as a JPEG or PNG because that’s what the ecosystem understood.
Then the industry pivoted.
Not overnight, but in waves: iconography got sharper, interfaces got flatter, brands got more “illustrated”, and vector became the quiet backbone of modern UI and editorial graphics.
“Illustrations made design cleaner and faster. But they also made meaning easier to stylize and harder to read.”
Read about why we moved away from bitmap-heavy visuals, what we gained (SVG, scalability, animation, speed), what we lost (immediacy, realism, shared interpretation), and whether the current AI image wave is the next step or a detour back to bitmaps.
Bitmaps were the default because they solved real problems:
If you wanted a dashboard to feel trustworthy, you often added realism: shadows, reflections, texture, high-frequency detail. Bitmaps delivered that quickly.
But bitmap-first design has recurring costs:
And there’s a subtle one:
Bitmaps are great at capturing reality — but reality is messy. The more photographic a system becomes, the harder it is to keep it feeling like one product.
The rise of illustration wasn’t only an aesthetic trend — it was a systems trend.
Once interfaces started prioritizing:
…illustration became the visual equivalent of a design system.
Isometric scenes were perfect for product marketing:
A less-obvious downside: isometric illustration often shrinks into noise. When you scale it down, the scene becomes “shapes” and loses the story.
Abstract characters became a universal language:
This is one of those behind-the-scenes drivers teams don’t always say out loud: illustration can be a brand-safety and logistics shortcut. No model releases, fewer “is this photo culturally loaded?”, fewer reshoots, fewer licensing surprises.
Over time, illustration styles got simpler:
The result: visuals got cleaner — but also more abstract.
Vectors didn’t win because they’re prettier. They won because they’re operationally superior in modern products.
SVG changed the economics of UI visuals:
Once teams started shipping motion as part of brand identity, vector became even more attractive:
Vector-based motion (including Lottie JSON) is also easier to integrate into component libraries: you can treat it like a reusable UI part rather than a one-off video export.
Illustrations can slow understanding when they’re doing the job photos used to do.
Here’s the design tension:
When the message is simple — “friendly”, “modern”, “creative” — illustration is perfect.
When the message is specific — “this exact product”, “this real place”, “this human moment” — illustration can become vague.
“The cleaner the picture, the more work the viewer does to interpret it.”
This shows up a lot in “generic character” marketing: it’s pleasant, but the user sometimes has to read the headline twice to understand what the company actually does.
Vectors shine for systems. Photos win for reality.
Here’s a practical decision grid:
There’s also the “authenticity pendulum”: many brands periodically swing back to photography because it reads as more human after years of polished illustration.
AI image generation is interesting because it’s mostly bitmap-first.
Even when the outputs look like illustration, the underlying deliverable is usually:
So in a way, AI is a return to the bitmap era — but with a new superpower: fast, custom, infinite variation.
The most realistic “next step” isn’t AI replaces illustration or AI replaces photos.
It’s a hybrid pipeline:
And quietly, there’s another direction emerging: AI tools that generate editable vector shapes (or at least layered outputs) so the asset can re-enter the “system world” instead of staying a one-off bitmap.
The story isn’t “illustration replaced photos.”
It’s: modern design became system-first, and vectors fit systems.
Illustration gave us:
But it also introduced a new risk: abstraction that looks beautiful and feels universal, while sometimes making the message slower to understand.
The next era will likely be less about choosing sides and more about building visual stacks: the right medium for the right kind of meaning — with AI acting as a new layer, not the foundation.
