When virtual reality first started, it was declared the downfall of human existence, like every new media is. But since it was crude and barely worked, most naysayers went back to attacking movies or comic books.
But then VR came back, and it came back good. And after a few years, it became great. And then a few years after that, it became realistic.
At that point, maybe, you could argue it was a problem, that this might lead to a lack of human interaction, and thus the birth rate would plummet.
Thank goodness for annoying pop up ads then.
