I wonder how many niches still use slide rules today. I'm currently training for my private pilot license, and many of the calculations for flight planning are still done using what is essentially a circular slide rule [1]. Having grown up in an entirely digital era it took me a good long while to get used to it, but there's a level of elegance baked into this multi-purpose device that it's hard not to like it.[1]: https://en.wikipedia.org/wiki/Flight_computer
