I have often wondered this as well. My own pet theory is that in worlds with magic users, magic gets used to solve the problems which technological advancements would otherwise be developed for. Of course, we get some fantasy lands like this, where magic itself was the major discovery behind the industrial revolution (see: League of Legends' animation, "Arcane", "Wheel of Time" novels). Then you have something like "Flight of Dragons" where science can be applied to how some of the magical elements work, but still are fundamentally incompatible. Almost like "Schrodinger's wizard", once you start analyzing the magic, it starts fading. There's a lot of different takes on it.
