Which gives most fantasy setting a very unrealistic/unbelievable feel. Humans have always used the tools at hand to improve their life, so why wouldn't they do that with magic?
It's not improvement that I mean, but the application of modern concepts to a Fantasy world. Most Fantasy worlds cannot handle modern thinking without breaking. And those that can end up SF with Magic instead of high-tech instead.
What happens to knights in shining armor once you combine modern thinking and historical knowledge about tactics and equipment? And then add magic to it on top? Firearms are the most prominent examples, but social and industrial changes are right behind.
LotR is the best example of how a Fantasy world cannot have scientific advancement without breaking down. How would LotR look if there had been one engineer with 10, 20 years time to prepare? Oh, look at the orcs getting gunned down and blown up, and poisoned, and so on. And then Aragorn gets replaced by a populary elected president.
The "Modern island/town/scientist gets transplanted into medieval/ancient/fantasy land/time and changes it" genre is pretty popular, and shows some examples of that.
SF worlds, on the other hand, usually thrive on applicating modern thinking, and thinking it through. I often have the impression that Fantasy worlds/novels have the effect (Whatever culture/hero the author wants) first, and then cobble together the cause, while SF worlds/novels usually deal with exploring the effects of a given cause.
