Thinking about it, I wonder why old film rolls were typically 30 shots. The film and the camera evolved hand in hand so it could probably have been almost anything but nobody was trying to make 100 shot film, or five, as a competitive advantage. Perhaps 30 was deemed to be the sweet spot for size, convenience, or just about enough for most needs.
Intriguing. Makes me start to wonder about other things we take for granted, like why vinyl singles play at 45 and not 50 or 35. How arbitrary were these decisions? I bet there's some interesting history hidden away here.
Sorry, I'm built this way, I can't help it.
