The bullying is still there, it's just moved online. If anything it's easier for the perpetrators, because they can hide behind anonymity, or create humiliating deepfakes - and so on.

The problem isn't phones, it's the addictivisation of social media and gaming. Being able to stay in touch with friends and family is potentially a good thing.

But it's currently implemented as a hook for psychological and chemical addiction, so that user attention can be sold to advertisers.

That is a problem, and I think we're starting to see a movement which will eventually end with these platforms being banned, or strictly regulated at the very least.

It's basically casino psychology applied to all social interactions. That is clearly not a good or healthy thing.

What seems likely is addiction mechanisms and social media will end up banned for kids. Loot boxes and daily login rewards banned from games, etc. Proof of age will be required for social media.
