I don't think this is anything new.
Physicists and scientists have often raised the concept of simulation. Eventually, the human race will simply crack AI and sensory replacement and therefore be able to create a universe inside a computer with billions of entities functioning with what they perceive to be their own consciousness (living their 'lives' effectively no different to how we currently live ours).
Ergo; it could be just as likely our own universe is such a thing as opposed to it being real. Some may even say it's more likely...
