The biggest hope I see is that the EU also wants to implement age restrictions, but with a lot more effort to get it right and make it compatible with a strong desire for privacy. Maybe that will make "proper" implementations easy and common enough that many of the downsides will be mitigated
Anyway, there are two questions here:
1. Do we need to verify the age of internet users?
2. How can we do it without sacrificing privacy of everyone involved?
