I’m sure by now you’ve seen the photo of Mark Zuckerberg grinning as he walks through a crowd of people rendered mindless by the irresistible escapism provided by the virtual reality headsets that’re strapped to their faces. Whether or not that was an accurate description really depends on how you interpret the photo, but even if you don’t get an Orwellian vibe from it, it’s easy to see why some people are concerned. Zuckerberg dismissed those concerns in recent interview with Die Welt, a popular German newspaper, saying that people are always wary of new mediums, and that people will come to embrace virtual reality once it becomes mainstream. As for when that’ll be, Zuckerberg believes it’ll be at least ten years before virtual reality really becomes mainstream.
