If you could chat and even have phone calls with your favorite starat any time, wouldn't that be exciting? Could it ever come true? With the rapid development of AI technologies, the virtual（虚拟的）humans might make it happen.
As we know, virtual humans now can be like real people. They can mimic（模仿）real people's voices, moves, and even copy their personalities. But what else can they do? And what can only be done by humans and not AI?
In fact, the idea of virtual humans is not something new. A virtual human is a human being that exists（存在）in the digital（数字的）world. It is created by making digitalcopies of the movements of a chosen human model and then accurately（准确地）rebuilding the figure in the digital world. With the help of 5G, AI, and VR technologies, virtual humans nowadays range from virtualreportersto virtual idolsand vloggersacross manyfieldssuch as radio, television, Internet, and business.
Virtual humans can do things that people cannot do in the real world, such as time travel. They can appear to be in different places and from different times in history.Imagine being able to communicatewith historical figures（人物）, learn from their experiences, and witness（见证）importantevents directly.
However,virtual humans have their disadvantages. They don't have much human touch（人文关怀）and EQ. These are something that only a real human can have. What's more,virtual humans can't team up and communicate with others in real time.
Virtual humansshow the power of AI, but they are not a substitute(替代) for humans. EQ, creativity, adaptability（适应力）, and personal touch that humans bring to the table are invaluableand cannot be achieved by AI.
