Virtual reality is when you immerse yourself in a completely virtual world through the auditory, visual and tactile senses and are completely separated from the real world, while augmented reality is based on the real world but adds more virtual detail to the real surroundings.

With regard to commercial uses, there are important considerations that should be taken into account. The first is the expected costs and complexity of developing solutions in virtual or augmented reality. Virtual reality is more complex as the programmer has to create a complete background using graphic techniques along with all of the auditory and tactile senses, and this requires hard-to-find technical skills and a very long time in order to develop the final product.

In terms of commercial uses, the health sector has used virtual reality to treat people suffering from phobias of various kinds, such as fear of crowds, heights and flying, where patients are immersed for the first time in such an environment to get used to it. Both virtual and augmented reality can help with phantom pain from an amputated organ such as a hand, as these technologies can trick the brain into believing that the organ is still present and the pain will decrease as a result.

The other potential uses are limitless and the imagination can be run freely, but cost and complexity can be a problem, and progress can be paralyzed. However, these unique skills and expensive equipment will become more available and cheaper, and in time will be available and affordable for everyone.

The actual life span of full-time employees in the metaverse world has practically increased. Instead of getting a job with a good salary after graduating from college, individuals can get rewarding career opportunities at a very early age, such as: Michael Syman, who got a job at “Meta” formerly known as “Facebook” at the age of 17, and is considered Tanmay Bakshi is the youngest programmer at IBM Watson at the age of 15, and many others.

Not only will the workforce be able to start their career journey sooner, but they can also continue to work for longer than is the norm in the real world. People usually need to retire at the age of 65 or 75, depending on the country in which they reside. It goes without saying that their skills and cognitive abilities may decline as they approach retirement age, but these individuals, during their careers, acquire a wealth of knowledge, experience, and contacts that can be passed on to the next generation. In the world of "Metaverse", the elderly will be able to sit comfortably and conveniently in their homes, teaching, holding meetings, mediating deals, and much more. With the advent of the concept of non-redeemable tokens (NFTs), they will also be able to create unique, salable pieces of art. Which ultimately means endless opportunities.
