The article begins with Bagchi's speculation on what it takes to be a professional. He is an experienced but amateur photographer and wonders if, in the future, people will considers themselves professionals of some discipline simply because they have the same equipment and software most career professionals have. The rest of the article illustrates that it will take much more than that to be a professional, currently or in the future.
The first mind of the future is the mind of discipline. Bagchi notes the many empirical studies which suggest that at least 10 years of practice are required to become a professional.
The second mind is that of synthesis. The future will require a professional to be able to correlate and compare ideas from many different disciplines: not just the ideas from your professional discipline (i.e. photography). Bagchi uses the visual metaphor of depth to describe the awareness of things beyond the immediate focus. Bagchi (well, Lens, the personified camera in the essay) also uses the ecology and economy of spaces he might choose to photograph to show how the professional must know something about the environment in which his/her profession is practiced.
The third mind is creativity. Lens (Bagchi) says that "tried and tested" applications are, by definition, "past." Therefore, the future professional will have to be creative, an innovator.
The fourth mind is the respectful mind. Lens claims that any significant problem in the future will require collaboration. Therefore, each professional must respect and learn from professionals in other disciplines in order to work together and solve a problem.
The fifth mind of the future is the ethical mind, which is the "capacity to certify the completion of one's own work." That is to say, the professional will be able to declare his/her work is true: empirically true, practically true, and/or of some universal truth.
Lens concludes that the future professional will also have to be globally relevant since the world is becoming more connected. This goes hand in hand with the respectful mind and the mind of synthesis which require the professional to be aware of the depth and integration of his/her profession with other professions, and the respect required to be open to interdisciplinary (and international) collaboration.
