And if so, what does that truly mean? We know that science, information, and technology are changing everyday, and most academics do not have time to keep up with their research as well as with their teaching responsibilities. So, academia (as an industry) often fails to prepare students for the real world, since academics are not always tuned into the latest information. Or some academics profess to have multi/interdisciplinary knowledge, but really only touch the surface on one area, while be dominant in another area. Also, we all know that no one really cares about the PhD dissertation. Few people will read your dissertation/thesis. So, what makes one an expert?
