Those are massive generalizations. Yes, plenty of engineers have terrible taste. Plenty of designers have no deep knowledge of data-structures. It's status quo

Those are massive generalizations. Yes, plenty of engineers have terrible taste. Plenty of designers have no deep knowledge of data-structures. It's status quo to compartmentalize talent. This attitude is so entrenched in my experience, that it's best to pretend that you don't know anything about design if you're working in an engineering department. But, a different level of insight in design can occur when the designer intimately understands the technological constraints.
