Which is better, big data or vr?

The problem with 1 and vr is that there are no products with high degree of commercialization. Microsoft's hololens is very powerful, but the model of this industry is not very understandable. It is said that Xiaomi wants to get involved, but if Xiaomi wants to get involved, he thinks he wants to be a platform. It is hard to say how ordinary applications can get a share in vr. Of course, the first application is the game, which means that vr will be the first one.

2. Big data is slowly entering its golden age. About two or three years ago, there were not many applications of big data in society, most of which were old-fashioned Internet, search, advertising and recommendation. But this year and next, it has been applied in some industries and there are many signs in society. Many companies that used to do tob began to think about using big data to better serve customers. It is difficult for these companies to recruit people with big data now. At present, the industry of big data still has a high technical threshold. To tell the truth, there are not many companies that can stably export services, which should be an opportunity.
