Its always fun to see how the future was depicted and then where it missed - a great example was Things to come where everything was aviation based - that was the emerging popularist technology then. So with this show we have the recognistion of computer based tech but alongside analogue instruments and good old CRT displays. Still the concept and stories are still quite passable in the main and still entertaining, which is the main thing.
If you compare UFO to say Star trek it hangs pretty well both in technology and story.
