Would you live in a virtual reality?
If technology and science ever got to that stage where you could live you're entire life in a 'virtual' reality, where everything would seem so real it felt real - in other words there was no discernible difference from real life - would you?
That in itself is no biggie - but what if in this virtual reality you could have any type of life you wanted, on an Earth/universe that you create and control.
So you could be a hero like superman (or even a baddie!) - or just a 'normal' person living a life that you've always wanted. It could be a world without any pain or suffering, no wars, no poverty (or the opposite if that floats ya boat!). You could basically do
anything you wanted - have the body/figure/partner/s you want
anything! It could be as perfect as you want it to be.
You could take your current memories with you - so all the people you want in your life could be there too. It would all feel so real.
Let's also assume that there were no flaws or problems with this system - it all worked perfectly.
So, if you couldn't tell it wasn't real and could swap... would you?
