Hi there,
the Unreal Engine exists since 1998.
I have played UT back in these years and the MapEditor was already amazing at this time.
You’ve got 18 years of evolved awesomeness in your hands and it still is on its unstoppable wicket sick godlike-rampage.
New Engine-Versions just mean: “many awesome technical improvements”, You still keep all your knowledge and you are just happy about things that became easier than before and about all the new features of course 
You need to keep in mind, BPs are treated like a “Prototyping thing” but you can already do pretty much everything with them if you are new to game development Even C++ Cross-Compiling for better performance is supported now. So guess what happens when they go full in and drop the “Noob-Friendliness”-Restriction of the Blueprints to support complex feature as well
With Blueprints you can focus on results instead of compiler issues and typos
Even creating an UI works better than some other UI frameworks I had to deal with.
Just my opinion as plain Software Engineer who is (well… now obviously “was”… 
) used to several Programming languages until I realized that UE4 is a full blown editor to work with
Just be welcome to the 2 Million devs that are using Unreal Engine. You can be sure, all of them want to keep everything alive until we finally get absorbed into the Unreal Engine created Matrix (Just think about why an “Unreal” Engine goes straight towards Reality and has already the Editor in VR and so on 
)
Happy Blueprinting Marooney
