Having the ability to create a virtual exact replication of various components and circuit designs without actual expenditures being incurred is priceless. The logic behind the use of simulations cannot be disputed. Although the actual technology does not exist today, it has certainly had a profound influence on the direction of our technological advancements. These various simulations all had one thing in common, they all afforded an unparalleled level of situational examination without the penalty of failure. The 'smart' virtual reality system was an invaluable tool with uses that includes personal stress relief, scientific simulation, tactical or even covert training. As a huge fan of Star Trek in all of its iterations, I have always found the logic and appeal of the use of simulators (Holodeck) as a means to arrive at a viable conclusion.
