Worst representations of computers in movies

I recently saw Jumpin' Jack Flash, the film, for the first time. It was enjoyable, but their idea of computers made absolutely no sense. It had that whole "if you're on one computer, you're on all computers" thing going for it. Whoopie's character's motivation was really bizarre. She's contacted by a man she's never met, and has absolutely no reason to help. She helps him repeatedly, and their various communications are bonkers. At some point, the computer starts reading off Jack's IMs to her, despite not having done that at all for the first half of the movie.

*Spoiler*
Not only does he not end up being a catfishing perv who abducts and muders her, he is actually exactly who he said he was, and they end up romantically involved.

I know it was the 80s, but come on.

What are other films where they get computers all wrong? Bonus if it's unforgivably recent.
