Should I be worried about screen time?

My 7yo has been watching more YouTube lately, mostly Minecraft building videos and some gaming content. It's probably 1-2 hours on weekdays, more on weekends. He's still doing homework, plays outside sometimes, reads. But I keep seeing articles about how screen time is destroying kids' brains and now I'm paranoid. Is 1-2 hours actually bad? Or are those articles just fear-mongering? Genuinely asking for a reality check here.
