This is all about innovation. Engineers discovering what is possible within technical limits. It’s just like car prototypes. Some of the ideas never make it and other ideas become a standard. You get reality by going through this phase. Something you as a technician should know.
Actually, it's not just "all about innovation" if one looks past their nose.
Sure, public displays like this one are radical portrayals of what is possible, along with eye-catching visuals with some "futuristic" styling thrown in.
However, it's not much different than going to an amusement park with impressive roller-coasters and colorful atmosphere.
It puts a seed of desire, excitement into human brains, in hopes of generating revenue for a company.
The subliminal mental manipulation of it all has been a marketing tool since before the Industrial Revolution.
And if you look at how its ultimately shaped society, you'll see that not everything has been beneficial to the masses.
Look at how some "innovations" are prone to abuse, such as smart phones, the internet, among other things.
Those things are touted as being convenient, worthy, important.
And they are, if used by respectable individuals.
However, the Reality is that sadly the world is not 100% respectable.
