my own personal tl;dr is that supercomputers are using enormous amounts of energy to solve problems in a digital way, so they think certain problems might be solved by designing analog computers

The analogy I think of is the difference between sending a text message to someone in the same room (digital) versus simply speaking to them (using the "analog computer" of your voice), this might be more efficient

or like in some cases it takes a certain amount of time and energy to transport data, whereas the "sneakernet" of just manually delivering a hard drive to someone might be more efficient: https://infogalactic.com/info/Sneakernet
