I can only speak for myself here but… A lot of things are taught in school. Most of them weren’t something that I use everyday and thus have forgotten about it (some more than others, of course).
Ohm’s Law would’ve been taught to me sometime during highschool (as the other commenter mentioned, I can tell you it relates to electricity but without looking it up I couldn’t tell you the actual principle behind it) - I graduated from highschool 10 years ago, and have not had a reason to “flex” that memory ever since then.
Hardware aside, to my knowledge no one is really actively developing any of the Switch emulators due to the prior legal action that was taken.
Now, eventually it’s possible someone might do it for the Switch 2, but I wouldn’t expect anything quick as whomever does so will very likely incur the mighty wrath of Nintendo’s legal team.
