I never really know what to think about this issue, On the one hand I used the internet unsupervised at around 10 and I think it was positive and I really do wonder if the extreme stuff such even murder videos and such are actually that bad for children in that lots of children would have seen execution's of people in the past. On the other hand I think the most negative thing about the internet today is social media and the sort of socialization it provides, The sort of way even fully grown adults treat influencers and the sort of trite conversations that you will now have with people on various topics and are only capable of holding these positions that youtubers have told them to. All of this has always existed of course but now the internet amplifies this and has connected too many people together and amplified the most stupid qualities of theses people and by extension society at large. Just look at the way are industry of supposed intelligent people have adopted the phrase 'token-maxxing' and other phrases that are just stupid. I think this is what is most damaging to children being exposed to that much stupidity that has been given far too much dignity.
