How do you imagine society would develop if dragons existed?

Stories involving dragons tend to be in medieval periods so maybe we can try to extrapolate forward in time a bit. Dragons could be from any mythologies or fictions of your fancy!

For my take, a dragon is a flying fire-breathing giant lizard with the size and toughness of a big building. I believe a critical factor is how tamable dragons are. If not at all, they'd go from something humans fear and run away from, then being hunted for glory and materials, then being protected in conservation areas to prevent going extinct. If they can be fully domesticated (like dogs), they could expedite for warfare, transportation and industrialized metalwork. The most interesting scenario imo is the in-between where they could only be partially trained. Maybe a skilled trainer can get them to behave 80% of the time but there's a low but significant chance that they get agitated and wreck havoc. How do we make use of them while ensuring safety and intervenability?

On the cultural side, we might not have as many myths and legends about dragons anymore. We might find the idea of giant flying fire creatures utterly mundane (phoenixes might be less interesting by relation even if they still don't exist in this universe). What would we mythologize about instead?
