It gets faster, easier and more responsive to business requirements.
There are a lot of ideas in technology that are widely accepted, particularly by younger, less experienced generations, as being The Best Way to do things. However, if challenged, most of those people don't really know why they believe that. They have never personally seen any hard evidence that The Best Way is actually better than known alternatives. They have never spent significant time trying those alternatives for themselves to gain first-hand experience of the pros and cons. In fact, their belief is usually nothing more than a matter of faith, a blind trust in the dogma of the day and the rhetoric they find on-line or hear from their peers or managers.
See also: OOP, design patterns, UML and round-trip development processes, frameworks, ORMs, XML, dynamically typed languages, more frameworks, TDD, NoSQL databases, and so on, many of which were either invented or popularised as a way to work around the artificial problems created by one or more of the preceding items.
Of course I'm being a little facetious here. But if you think I'm entirely kidding, just spend a few minutes with Google and see how much advocacy there has been for each of those ideas in their day and how much actual data there has ever been to justify that advocacy. And really I'm being kind here, because you talked about things that are supposedly "faster, easier and more responsive to business requirements" and I didn't even mention words like "agile" or "craftsmanship" in my list.
If you don't embrace change in the IT industry then get out. Because you simply won't survive.
I embrace using the right tool for the job. Whether it's new and shiny or old but tried-and-tested doesn't really matter, though if I had to pick one or the other for some bizarre reason, I'd pick tried-and-tested eight days a week. There have been only a few truly significant advances in the past decade or two, but very many technologies that were initially much-hyped but then failed to stand the test of time for exactly the reasons that critics outside the hype bubble had always predicted.
Will our profession ever stop being fad-driven?
