Odin's having an existential crisis wondering if he failed as a mentor because he kept calling his son's favorite language "C hashtag" instead of "C Sharp." Plot twist: they're the same thing, just pronounced differently. Here's the thing—literally everyone who's ever encountered C# has gone through the "hashtag vs sharp" identity crisis at least once. It's written with a # symbol, which the entire internet has trained us to call a hashtag, but Microsoft decided to get all musical and fancy by naming it after the sharp symbol (♯) in music notation. Because nothing says "enterprise software development" like pretending you're composing a symphony. Fun fact: The # symbol isn't even technically a sharp symbol—that's ♯, which looks slightly different. But good luck typing that on your keyboard, so we all just use the pound/hash/number sign and pretend we're sophisticated.
