That was built by engineers not by designers or by UX guys who do "research".
So my argument stands.
The best UI/UX is the type that gets out of your way. That is If there was a way to do away with UI and Ux all together and simply control our machines with thoughts or electrical impulses that would be the best UI and UX there is. Engineers know this that all of that stuff just gets in your way, and if they don't know it they quickly learn it through seeing their users interact with their software.
We don't need a bunch of people standing around doing "research" telling us that.
