Who saw this coming? Analog computers 😂 I'm joking - they actually had been used quite a bit all along, but they now get a new life thanks to significant technological progress. It's extremely important to understand the strengths and weaknesses of digital vs analog technologies, so the right one can be picked for each application. Digital tends to be much easier to implement, but it can have significant limitations. Analog is much close to how reality works. https://www.eurekalert.org/news-releases/1037713
