The Half-Life of Screens

For most of the last two decades, digital strategy started in the same place: the screen. A homepage, an app flow, or a checkout page. Teams designed the interface first, then worked backward into the features that would live inside it.

‍

That starting point made sense when a website and an app were some of the only places a brand met a customer. It makes a lot less sense now.

‍

Look at how apps like Spotify or Apple Music actually work. The experience has very little to do with any single interface. You get a recommendation on your phone, play it through a speaker, skip a track from your car, and pick up the same queue on a watch.

Rideshare apps are another example. A ride used to live entirely inside an app screen. Now it's a push notification, a ‘Live Activity’ on a lock screen, a glance at a watch face. The app itself is just one entry point into something bigger.

‍

The screen isn't the product; it's a temporary way of presenting the product. That gives every screen a half-life. 

‍

The interface you build this year is a reasonable bet for the next few years, not a permanent structure. Interfaces are proliferating across web, app, wearable, voice, in-car, and now AI assistants that complete tasks on a customer's behalf without a screen at all. The average household already connects upwards of 20 devices to the internet, according to Deloitte's research on connected consumer behavior, and that number is only trending up. Every one of those is a potential surface a brand needs to show up on.

‍

So where does the durable investment actually live?

Here's where a lot of brands get the wrong idea. There's a real and valid conversation about the commoditization of the front end. Templated builds, faster production, and cheaper websites are all real, and it's happening. But it's a mistake to extend that same logic to the systems underneath the interface. 

‍

The infrastructure that understands your customers, organizes your content, and powers decisions across every surface a brand touches is not getting simpler or cheaper. If anything, it's becoming the more valuable half of the investment. Gartner projects that by the end of 2026, 70% of organizations will be mandated to adopt composable, API-first infrastructure over monolithic, single-purpose systems, up from 50% just three years ago. That's not a story about interfaces getting cheaper. It's a story about the layer beneath them becoming the priority.

‍

What actually holds up as interfaces change?

Start with capabilities, not their interfaces. Before deciding what a page or app should look like, define the small number of things your digital ecosystem needs to be excellent at. 

• Understanding your content and products
• ranking what matters in a given moment
• understanding a customer's context
• searching and summarizing information
• recommending a next step
• deciding when and where information should show up at all

Build one shared context. Your website, app, AI-facing content, and whatever comes next shouldn't each rebuild their own understanding of the customer, the content, and the business from scratch. That understanding should live in one place and be available everywhere.

‍

Separate logic from presentation. Ranking, personalization, recommendation, and decision logic should be built to operate independently of any single interface. The presentation layer can change completely without touching the intelligence behind it.

‍

Preserve optionality, not predictions. Nobody needs to guess the next interface correctly. What holds up is capability that stays useful no matter which interface shows up next.

‍

A useful test for any major digital investment: if this screen disappeared tomorrow, would the capability behind it still be worth something? If the answer is no, the investment was in the interface, not the business.

‍

That reframes the roadmap conversation for any brand thinking seriously about its next stage of growth. Most teams keep one list: what experiences are we launching. The stronger version keeps two: what experiences are we launching, and what capabilities are we building that will still be valuable after those experiences are gone.

‍

The screens will keep changing. The value lies in what's underneath them.
