Isn't the main hindrance the cost and speed of development: You can buy an off the shelf digital FPGA/CPU chip/board and get one of a thousand software engineers to start building a prototype tomorrow.
An analogue solution is a much costlier and time consuming solution.
The area where I saw analog computers that made sense is in CCTV cameras. Installing an analog board into a camera to identify shapes is cheaper to be done on camera vs sending all video for processing.
Think manufacturing QA, retail foot traffic, or similar applications.
