There is no way of knowing when it will come in handy. The trial we presented twenty years ago would be tried much differently today. Jury expectations change. Now they expect graphics and not just vivid descriptions. Now they expect timelines and not a recitation of historical events.
People are products of their environment.
They perceive differently today. They will perceive differently tomorrow. As an advocate, it is your job to understand how to present your case effectively, so that it will be understood in the most favorable light and remembered. Use the technology to prepare yourself for the trial of today. You need to use the tools available to give you an edge.
