Your comment reminds me of a couple things. On the topic of RAM, I was recently researching the vintage IBM 650 computer (1953). You could get it with Random Access Memory (RAM), but this RAM was actually a hard disk. I guess IBM considered the disk to be more random access than the rotating drum that provided the 650's main storage. One strange thing is that the disk had three independent read/write arms. Unlike modern disks, the arm could only access one platter at a time and had to physically retract to move to a different platter. Having three independent arms let you overlap reads and seeks.
As far as "fuzzy logic", there's a whole lot of history behind how that ended up in your rice cooker. In the 1990s, fuzzy logic was a big academic research area that was supposed to revolutionize control systems. The basic idea was to extend Boolean logic to support in-between values, and there was a lot of mathematics behind this, with books, journals, conferences, and everything. Fuzzy logic didn't live up to the hype, and mostly disappeared. But fuzzy logic did end up being used in rice cookers, adjusting the temperature based on how cooked the rice was, instead of just being on or off.
