Virtual Reality,Natural Reality and Information World:Discuss with the Author of the Final Collapse of Realism

In virtual Reality,information is virtualized instead of reality.The virtual reality world must take concrete material world as its carrier;therefore it is impossible for virtual reality to deconstruct the material world.The design and construction of the virtual reality world is a practical social project and the nature of the world should be explained at this level.Zhai Zhengming tries to avoid judging the property of virtual reality world through vivid individual experiments.This method is not reasonable and consequently the conclusion that realism has thoroughly collapsed can not hold its ground.
