The original Nintendo Switch uses Joy-Cons as game inputs, but those controllers actually run their own real-time operating system with its origins in the 80s. Not only has Nintendo never mentioned it, it’s barely been reported outside of Japanese media. The Switch, a SIM card, a Bosch dishwasher (maybe), and every Intel machine you’ve bought in the last decade all have something in common: they’re all running operating systems that aren’t advertised, talked about, or, in some cases, even admitted to.
