Well I mean if it was reality it would be called "reality". It's a virtual representation of reality, which is why it's called "virtual reality". A video game isn't the real world, it's a virtual representation of a world, so it's called a "virtual world". And Nintendo's head-mounted video game system from the 90s wasn't a real boy, it was a "virtual boy".

What I'm getting at is this argument stems from semantics. Of course VR is never going to replace the real world. That was never its intent. The goal is to not replace reality but rather to simulate it. That's why the name has "virtual" in it.
