The memory of how we work will endure beyond the products of our work.
When you're trying to solve a problem on a new product type, you become completely focused on problems that seem a number of steps removed from the main product. That problem solving can appear a little abstract, and it is easy to lose sight of the product.

As consumers we are incredibly discerning, we sense where has been great care in the design, and when there is cynicism and greed.
