Professional Training Simulations
Many people think of flight simulators as realistic games. The reality is that simulators were developed to allow pilots to train, and make mistakes on the ground rather than while in a fragile vehicle somehow suspended in air. Professional simulations are used for training in many fields: trucking, shipping, medicine, military, utilities, etc. Prior to computers, the training was mechanical and approximate. As computers advanced, the realism advanced, and the education and learning shifted to digital simulations, sometimes in physical simulations like cockpits. The nature of the lesson changed. The debate about which is better continues, though the direct costs are significantly lower. Crash a computer, lose a bit of data. Crash an airplane, much more value is lost.
