"Today's Weapon, tomorrow's convenience." You can't say that about many things, but you can say it about a few.

This is exactly how it turned out, but it took longer. Much longer. I remember cars had phones in movies in the 60s, but that was just for businessmen and villains. More common by the 70s, but it was still a mark of prestige and wealth.

Now they're the cause of half the accidents on the road.
