In my opinion, no single design is apt to be optimal for everyone.

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.

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

The hardest part of design ... is keeping features out.

The current paradigm is so thoroughly established that the only way to change is to start over again.

It is relatively easy to design for the perfect cases, when everything goes right, or when all the information required is available in proper format

I prefer design by experts - by people who know what they are doing
