It's more or less highlighting another example of cool-looking technology that the primary advantage is that it looks cool, rather than more functional (there are some valid applications for 3D data visualizations vs. 2D data visualizations; these aren't it). Business stakeholders like it when things look cool.
There's a difference between an interface that allows for this in a very convenient way and something that is made mostly to look cool.
When many people are working in virtual workspaces in 10+ years, this becomes basically second nature. Right now, yeah, it's very hard to imagine people putting on a headset
just for the sake of visualizing some graphs better, but when that headset is being worn many hours a day, it becomes easy to add in an extra little thing.
It's kind of the nature of spatial computing as it exists today. Very few people really find themselves using it because the interface has a long way to go and wearing bulky, usually wired, headsets is not recommended for doing work. Eventually, it could be extremely common.
