Technically, the jury is still out on this. I don't think anyone's done any kind of study of how childhood YouTube brainrot affects their long term outlook during adulthood, simply because YouTube brainrot is too new. For what it's worth, if I had to bet money, I'd agree with you that "socialized, bonded, explored, etc." is better than YouTube, but I don't think this has been proven yet. It's just a gut feeling.
