[Fallout] Why are computers so primitive?

We have nuclear fusion powered cars, advanced energy manipulation, highly advanced cybernetics, etc. Yet all the computers are still big clunky machines with tube screens and shitty interfaces. What's up with that?

Fallout is not set in the same universe as ours.  Aliens have been observing Earth since at least the 1600s, which caused a ripple effect that resulted in the transistor never being invented, among other things (First man in space was 'Merican!). Instead of spending time developing clunky and slow computers, efforts were instead invested in developing the fields of robotics and atomics.
