The best interface is the one you don't open

A friend wanted to know whether the 14th of next month falls on a Friday or a Saturday.

His phone has a calendar app. Two taps and he'd have the answer in a second. Instead, he opened ChatGPT and typed: "What day of the week is the 14th of next month?"

It took about ten seconds. He didn't mind at all. He smiled when the answer came back.

It's a little funny. It's also a big clue about where software is going.

We've stopped going to the app

AI is getting more capable every few months, and more people use it every day. But the most interesting change isn't how smart it is. It's how people are starting to reach for it.

My friend didn't want a calendar. He wanted an answer. Opening a chat and asking in plain words felt more natural than finding the right app and tapping through its screens. Even when it was slower.

That's the shift. People don't want to learn your software. They want to say what they need and have it done.

A real assistant, not just a chat

Chat is only the beginning. Late last year, a developer named Peter Steinberger released a personal project that is now called OpenClaw, an open-source AI assistant that runs on your own computer and talks to you through apps you already use, like WhatsApp, Telegram, or iMessage.

What makes it different is that it doesn't just answer questions. You give it a goal, and it goes off and works on it in the background: reading, checking, organizing, following up. When it's done, it reports back. Like having a real personal assistant, except it never sleeps.

Once you try something like that, opening ten different apps to get one thing done starts to feel old.

The interface fades away

Golden Krishna wrote a whole book about this idea years ago, The Best Interface Is No Interface. AI is finally making it practical.

Here's what I believe will happen. Most people won't open a separate app for every task anymore. They'll have one personal assistant, either its own app or living inside the chat app they already use every day. They'll tell it what they need. It will use the software for them.

The apps won't disappear. They'll just move behind the assistant, the way the engine sits behind the steering wheel.

Built for developers, coming for everyone

There's one catch today. Tools like OpenClaw were built by developers, for developers. Setting one up means installing things, connecting accounts, and understanding a bit about how it works. Most people will never do that.

That's exactly why I think the big tech companies will race to build this for everyone. A personal assistant that's simple to start, safe by default, and already connected to your messages, calendar, and email. The first company to make it feel effortless will change how millions of people use software.

What this means if you build software

If people stop visiting your app, the question changes. Not "How beautiful is our interface?" but "How easily can an assistant use what we built, on someone's behalf?"

Your future users might never see your screens. They'll just notice whether their problem got solved.

And honestly, that was always the point.
