We currently live in an age where technology is slowly taking possession of our homes. Something that I seem really sad is to see families reunited, and that each member is looking at his cell without setting any conversation. I dare say that technology improved the communication but, got worse quality.
I do not consider that evade the reality is a good choice, sooner or later we have to face our problems and doing so gives us maturity and growth as a human beings. I know that many people use this kind of thing because it helps them get ahead, for example, of a strong depression, but in my opinion I think that for everything there is a balance to avoid falling in excesses.
We can compare Oasis with the social network Facebook, for example many people publish a lot of nonsense things, or worse even, making public everything that they do (to where they leave, what they are eating, what bought, etc.) without seize the opportunity to enjoy their activities. Now the problem is that many people hide behind a computer and displayed through it as something they're not or worse even, looking for acceptance of people through likes.
It's interesting how most futuristic novels narrate a world desolate, where everything is dead and there is no hope for humans. I do not know if this is a coincidence, or if indeed we are leading the world to a similar situation, from my point of view I think we are not far away from becoming in a society like that show us some books.
Of course it is possible to have a world like Oasis, augmented reality is something in which many experts are working, and the technology is progressing ever more quickly, so we should not doubt that in the future we will have access to our own Oasis.
