The profession of architecture has changed significantly, but the perception of what an architect does has remained much the same. So what's the big deal? As is often said, perception is reality, and therein lies the problem. What architects do now no longer agrees with what the public, and even architects themselves think they do.
Most people don't really understand what today's architects do. They think architects know about planning and design, and how to create buildings that are responsive to owners' needs. In that, they are correct; architects by training learn how to do these things, and they do them well. Unfortunately, most people also believe the architect is still the Master Builder, who knows everything about construction materials and methods, actively manages the work, and tells the contractor exactly what to do. And in that, they are sadly mistaken.
