VR art might help us experience the world aslant, so to speak, from the perspective of other people or even other beings. I can’t be a whale in the real world, but I might be able to be one in VR. The downside of immersive media is the same as the upside: immersion obscures imagination.
Movies are already more constraining than novels and reality media will be even more constraining: you will only see and touch and hear what the reality creator wants you to see and touch and hear. As we move up the immersive ladder, we also increase the resource asymmetry between the creator and the consumer.
A reader of a novel is roughly equal to the writer: they too can pick up a pen and start writing (if only they had the skill to do so!), but it’s hard to create a scene in response to a movie and will be even harder to create a compelling VR experience: the costs of reality media bias them towards the largest studios.
