Have I just....matured (?) or Is it true that new manhwas don't have the same appeal to them..?

I took a long break from mangas/manhwas/manhuas in general and now that I'm back I just can't see the appeal in them... Like I feel like I'm wasting time but then again what do I do in my free time. This is all I did ever since I was 12 years old . I never thought that a day would come when I would willingly stay away from these.
