Analog was before, though. General computing was never realized using those architectures; granted, they were mechanical in nature, so that is a big ask, both figuratively and literally.
Maybe we could create continuous-valued electrical computers, but at least state, stability and error detection are going to be giant hurdles. Also, programming GUIs from Gaussian splats sounds like fun in the negative sense.
The important difference is that all those early analog computers were either bespoke or suited for a very narrow subset of tasks, like fire control computers. They were very far from general purpose computers, and that is the reason the von Neumann architecture dominates today: we are free to change the operation of the computer without literally changing gears or re-wiring all logic paths. Before, the hardware was the software.
