Grinding isn't for everyone, and even when you grind a lot it can still feel unrewarding. I'm definitely with juanelric here, Genshin's grinding doesn't feel very rewarding in my opinion as well. There's other games where I feel the grinding is more so rewarding, there's also games that don't require any grinding and those are the most fun games for me.
Also often times one of the hardest parts of grinding in games such as Genshin is keeping up on the constant daily requirements and engagement, which is time consuming, and often I find my time is better spent elsewhere. Plus again there are a wide variety of video games out there, if people don't enjoy grinding they can certainly love video games while avoiding that factor. People are valid for not enjoying grinding, and people that enjoy grinding are also valid.
