Captain Kirk wants an upgrade
"The flip open communicators were very like modern cell phones are."
The flip-style was based on Trek. But...
Modern teen: Hey, dood, Nice retro cell! You got 4g?
Captain Kirk: Huh?
Teen: What's the bitrate on video downloads?
Kirk: Um, I don't get video.
Teen: What? Well, what do you have? You can at least Google, right?
Kirk: Um... phone service and, uh, GPS. Oh, and I can talk to the operator at the computer on the ship.
Teen: !!!!!!
Absolutely no one imagined what the cell would do. Nor even now imagine what its descendents will do.
I am so glad I live in the future.
