>>It's possible to create a lot of useful things that don't have good design.

Usefulness is good design.

No, it's not necessarily. You can have a product that produces a good result but isn't easy to use. That doesn't make it not useful.

If we are going to split hair, I would argue that good design is mostly reasoned with theory, usefulness is more about pragmatism.
