Correct me if there is a flaw in my logic but let's assume that in the future :
-Realistic VR is a thing
-Brain uploading is a thing
-People can chose to permanently remove themselves from physical reality and live in cyberspace in MMOs worlds.
Doing so, they would put themselves directly under the control of whoever is in charge of said system.
Virtual universes having no real limits that person has now godlike status and gets to decide absolutely everything from the gravitational constant to the gender of frogs.
You may have signed up for a life in VR Paradise Island but there is nothing preventing the person in charge of your matrix to unleash floods and rivers of blood upon your world. And having uploaded yourself there's nothing you can do unless other "gods" wage a war in Heaven to liberate you.
We could call those well-intentioned gods "judges" and the heaven would be the real-world courtroom which is now located on a different dimension as far as you're concerned.
So, by these criterias is it fair to say that our advance in technology will make the concept of god a very real possibility ?
