Every time I see this video posted I watch it again from start to finish. Amazing what could (can!) be done with purely mechanical components.
That vid brought a few internal chats about computing. Since it's clear those things are computing advanced function in real time (with noise though), streaming physical changes downto the linkage graph, no side effects if you haskell-squint hard.. digital computers are a different take on computing, they were timeless, memoryfull at first.. and along the decades it seems we were all seeking to bring back automatic coupling (reactive recomputation) on the foreground.

An early example of this (an electronic computer in the 1940s!) seems to have been:
Hollerith and discrete calculating machines were more about unordered data analysis. Static batch of input, chunk it the way you want, forward, backward.. doesn't matter. Very freeing in a way. I can understand why digital computation wiped the market, no noise and no constraint.. how nice. Until it starts to produce spaghetti bowls and crawling insects.
In that alternate universe, maybe Swiss watchmakers are the ones driving innovation in computing.
