In ML/AI space, at least some people thing analog computing is the next big thing, https://www.forbes.com/sites/karlfreund/2021/09/23/ibm-resea.... It hasn't taken off, yet, though.
Honestly it seems like a perfect application. Neural networks are analog systems. An analog computer can represent neurons very accurately and the entire network is inherently parallel, for free!
I can't wait to see what comes out of this research
