I'm beginning to wonder if social media really has caused kids to miss key developmental stages. Parents being on their phones has led to kids hearing a substantially reduced vocabulary, these kids also receive less interaction from their parents and interact less with their environments and other kids. This stuff is really important for brain development, and we've replaced it with an iPhone.
I don't think social media started this, just accelerated the trend. I do think commercialized media for decades now has really been a driver of insipid banality.
