Article is what seems like a good introduction to a longer article, but then it doesn't go anywhere. I thought it would talk about how modern rice fancy rice cookers work. The old fashioned kind is very simple though: just a heating element, aluminum bowl, and thermostat. I'm amazed to hear they weren't around before the 1950s, if that is true.
The Atlas Obscura article it links to is a lot better: https://www.atlasobscura.com/articles/rice-cooker-history
I'd support changing the thread link to that. The ghost.io article is mostly drawn from it anyway. It is almost like a splog.
