Someone can be talented at both, expert in both and innovator in both. The real talent comes in doing them at the same time, within the same project and timelines. The same can be said for that of a writer who understands the context of their story well enough to doodle their vision on paper. I design quickly and efficiently when I start from code. And it shows in the end result. It is often stark, linear and lacking of anything truly distinct upon initial inspection. I design with more empathy and articulate information differently when I work with visual information first in an attempt to tell a story or create an experience. This may include starting with pencil and paper before using a computer. I'm surprised daily, by those who are lucky enough to be successful at both.
