5 Pocket Calculators
Kraftwerk- "Taschenrechner" (German)
Kraftwerk - "Dentaku" (Japanese)
Kraftwerk - "Mini Calculateur" (French)
Kraftwerk - "Pocket Calculator" (English)
bonus: Pizzicato Five - "Contact" (from 1995, a kind of live mashup of "Pocket Calculator" with Brigitte Bardot's "Contact")
No-one uses calculators anymore, but otherwise the album from whence this song comes, "Computer World," pretty much nails it. We do all have computers, which seems obvious now, but sci-fi writers or futurists never spoke much about home computing or the internet. The future was supposed to be all about space travel. I have a book from 1979 with predictions for the year 2000, and it's a lot of: moon colonies, Mars landings, etc. At least Isaac Asimov said that we'd be able to read newspapers headlines on TV, which was close. But the song "Computer Love" even predicted internet dating. Kraftwerk for the win. And these retrospective shows they've been doing lately are their victory lap.
Those men-machines from Dusseldorf also did an unreleased Italian "Pocket Calculator" for TV:
