Virtual reality is a new technology. “The term “virtual reality” was first used in a science-fiction context in The Judas Mandala, a 1982 novel by Damien Broderick.” – Wikipedia. So and now there are devices that give us an opportunity to plunge into this reality.
Nowadays Virtual reality used in several industries, for example medicine.
“Therapeutic virtual reality (VR), the use of the immersive, computer-generated technology in medicine, is on the fast track to widespread use. In some hospitals and clinics, your doctor can already prescribe a visit to a VR world to ease your pain or anxiety or to explain a complex medical procedure or condition.” – source https://www.webmd.com/a-to-z-guides/features/virtual-reality-medicine.
or some surgeons can practice before a complex operation and in some hospitals doctors already use VR during operations, where is impossible to use human hands and thumbs.
“The virtual reality system is helping train residents, assist surgeons in planning upcoming operations and educate patients. It also helps surgeons in the operating room, guiding them in a three-dimensional space.

On the other hand, VR used in the entertainment industry: games, videos, movies and so on. It gives customers new sensations, but it could provide an addiction to this games. In VR games people could be anyone: a person, an Alien even a rock with Legs. And this possibility to be anyone could be dangerous. This problem was showed in movie “Ready player one” where people were playing in VR game and did not work, just playing this game.
Until everyone get such VR games it is hard to say if this technology would give more Pluses than minuses. Personaly, i believe that it would bring more pros, because i can compare this technology with telephones. everyone use them now, but few decades ago people said that we would not live normal live with them, we would be playing all the time and we need to destroy them. And now, telephones helps us in live, we could communicate with our friends and travel during our work, if it is online. So i hope the same thing will be with VR technology)
