“If it’s made out of electrical components then you should be able to scale it down to a microchip,” he says. “I think that’s where they’re going with this.”

Mind.Blown. This could be a very interesting development.

Which would be best for this - ASIC,FPGA,VLSI? Something else? for a rapid prototype setup?

None. This is an analog computer. There are devices such as the field programmable analog array (FPAA) however that may be suitable.

https://anabrid.com/ is working on programmable analog computer on a chip though. So far they are only selling discrete hybrid calculators and an educational "cheap" analog computer. https://the-analog-thing.org/wiki/Main_Page

Those FPAA seem just to be programmable analog filters not analog (or hybrid) computers.
