Electrical engineering's identity crisis - when does a vast and vital profession become unrecognizably diffuse?

More than a century ago, electrical engineering was so much simpler. As electrical engineering begins to blend with various subject areas such as biology, quantum physics and materials science to establish entirely new disciplines and branches of electronics, there are concerns that the EE profession may become "diffused". This paper provides a perspective on the essence of what it means to be an electrical engineer in today's rapidly evolving world.
