How close are we to building Valerian’s virtual Big Market?

In Luc Besson’s science-fiction fantasy Valerian and the City of a Thousand Planets,

one of the major action sequences takes place in a space called the Big Market. It’s a sort of hyperdimensional mall where tourists show up in busses to strap on VR gear and wander around in a desert, while virtually experiencing a promised 1 million shops. Valerian’s Big Market has some technology that we aren’t likely to achieve anytime soon. It isn’t just virtual reality: the stores exist in a different dimension, and shoppers can access their purchases instantly by yanking them through a dimensional portal at the checkout stand. But apart from instant delivery, most of the market could be adapted to real-world virtual reality technology, and in that sense, it has some interesting potential. The Big Market is essentially an Amazon-style one-stop space that brings everything together for consumer convenience. But unlike Amazon, it could potentially let shoppers see the actual size, shape, colors, and quality of the things they’re buying, and could let them browse more efficiently in product-filled spaces, instead of clicking from page to page. That seems like something sellers might want — the chance to turn the dying American mall into a tech-enhanced purchasing paradise. But would buyers want access to a Big Market? Can we make one, and should we?                                                                                            https://www.theverge.com/2017/7/26/16027946/big-market-valerian-and-the-city-of-a-thousand-planets-virtual-reality-shopping
