mmmm
Age verification is still a good and needed thing.
I as an adult can decide if I want to use a service or not, and if I think a service doesn't deserve my ID, I simply don't use it.
I also don't believe people will use the Internet much in the coming years. Everything will be polluted with AI video, text, audio. Why would anyone use that anymore?
Internet will be used for governmental services, banking and maybe messaging like Signal. But all the other stuff? Nah, i am very sure the Internet and it's impact will fade.
And if people will still use it, knowing it's all hallucinations of AI, we as a society have bigger problems than surveillance.
