Most people know the tale of the blind men and the elephant. Each describes a part of the elephant. The elephant is said to be like a pillar by the blind man touching the elephant's leg. The one touching the elephant's tail says the elephant is like a rope and so on.
Now, let's substitute so-called futurists for blind men in this tale and you get something even less reliable. Futurists are the soothsayers of our age. Of course, futurists have eyes to see at least. But they, like the blind men, almost never see the whole picture.
And, in this case they are giving us a description of something that is not even there for them to examine. The future doesn't exist. It's a mere concept. Unlike the blind men, futurists aren't really describing part of a whole.
