Those working in the industry often know what's coming. What they often get wrong is how it's economically deployed, when it arrives, or what effects it will have.

E.g. the first articles on capacitive touch screens dates to the 50's, and the "flat-panel" Aiken tube display dates to the early 50's as well:

Seing the potential of going from normal TVs to that, it's certainly not a big leap to assume they'll get even thinner and smaller.

That movie is very special. A lot of it’s predictions like flat LCD screens, personal IFE on airplanes, iPads, and kids messing around on FaceTime are so mundane now it’s easy to overlook them when watching the film with a 21st century set of eyes

Yet its central “prediction”: that human travel into space would progress forward at a comparable rate to what was accomplished in the early 60s, was wildly off.

As was pointed out in an earlier comment, 2001 really only got the economics of space travel wrong. It's possible that we could have done it, technologically speaking, but that it just would have been a huge waste of capital.

And also after the Mother of All Demos in December 1968.
