What analog technology would you like to see make a comeback?

Got the idea from watching Captain America again. There wasn’t one single bit of digital anything in there. The designs were all pretty cool, too.
Upon reflection, I realized that I have two rotary-dial phones in the house that have likely had little or no maintenance over the last 50-odd years, and work splendidly. I’d like to see more of those. As a bonus, they’re not compatible with phone trees that require touch-tone phones. Bring them back en mass, and we might see an end to their automated tyranny!
