"a dystopian fascist museum" - ???
By that they do not mean the Polish museum, but the museum of their "friends' awesome FMP"... but I don't know what FMP means. Maybe "Fiction Media Project"?
Analog computers are totally a thing though. My dad used to build them in engineering school.
They were not general purpose at all. They would be more aptly named simulators. You'd use discrete electric / electronic components - capacitors, inductors, transistors - to model a specific differential equation system. You'd use trimpots to modulate parameters in the equations and a square wave generator to to trigger the "calculation".
Output was in an oscilloscope, and you'd have to interpret that to figure out what that meant to your particular computation.
