>>62645423In vtubing context, he's kinda right if you want to have a girlfriend and live a normal life. Watching streams wastes your time that you could have used to socialize, work out, and get a real girlfriend.
But if you just want to feel entertained after a long day of hard work or you don't care about being single forever and not having a wife and kids then he's wrong. It's also worth noting that everyone has their own hobbies, and maybe by watching vtubers they can feel happy without having to deal with human conflicts that happen in real life relationships. But vtubers don't stay forever, they're like a time bomb, and before you know it, they will graduate and your heart will be filled with void and loneliness again.
