I think a successful company is one where everybody owns the same mission. Out of necessity, we divide ourselves up into discipline groups. But the goal when you are actually doing the work is to somehow forget what discipline group you are in and come together. So in that sense, nobody should own user experience; everybody should own it.

Also note that invariably when we design something that can be used by those with disabilities, we often make it better for everyone

When a device as simple as a door has to come with an instruction manual—even a one-word manual—then it is a failure, poorly designed.

In the university, professors make up artificial problems. In the real world, the problems do not come in nice, neat packages. They have to be discovered.

Forget the complaints against complexity; instead, complain about confusion.

A big ethical question is what happens after people stop using the device. Does it degrade the environment? Could it have been designed so it would actually be good for the environment?

Simplification is as much in the mind as it is in the device.
