In the same way an iPad is, I guess. It's got a browser, you can install apps and do a surprising amount of stuff with it. As-is though, it's not going to change anyone's mind about VR work. You'll still want your laptop and keyboard.

All this is why I'm not holding out much hope for non-entertainment AR applications. Even if your headset is great and as simple to use as unplugging it and putting it on, you won't daily-drive it unless it's better than everything else. For programming, I don't think any VR headsets are going to offer better experiences than Intellij or VS Code.
