Mentally, yes. But some of those children are in the bodies of middle aged men.

Honestly, I think it really depends on the spaces. Meme communities and video game communities? Full of kids. Politics and news? Maybe a few teens be trolling, but it’s mostly just dumb ass adults. Super crazy niche hobbies, especially those that take years of work like building your own electronics? If there are kids there, they are geniuses and you’d probably never know they’re a child.

I’m 38. I guarantee I probably sound like a kid when I’m gushing about a game or something I like, since everything I am into is generally thought of as for kids. Video games, comic books, Lego, etc. And I constantly equate other more serious things to these things I am more familiar with when I see parallels.

Not to mention autistic people are both extremely present online and in technical fields, but also can be perceived as child-like.
