Question

Some engineers design electronic products, such as dvd remote controls, with so many buttons that these devices are ultimately useful only to other engineers. as one writer noted, "people who design products are experts cursed by their knowledge, and they can't imagine what it's like to be as ignorant as the rest of us." this is known as the curse of knowledge.

Answer 1

That statement is true

The curse of knowledge is a bias that formed because we have deeper knowledge about a specific knowledge compared to other people.
another example would be:  the majority of wealthy Bankers have their own Physical deposits to store some part of their wealth because they understand the Risk that could be caused by failing Banks.
