As usual 95+% of people commenting have no idea what is actually in the California law, and so are commenting about things that have nothing to do with it.
Different states, countries, and multi-country organizations that have legislated in this area or are working on legislating in this area have went with many different approaches. These differ in their scope, how age is verified (or even if age is actually verified), what documentation is required (or even if documentation is required), whether they apply to the web or to apps or to both, whether they make anonymous use harder or not, how much if any sensitive information they disclose to the apps/sites that need to check age, whether they could allow government to track your usage, and in other ways.
Most ridiculous are the comments that after saying how bad it is (clearly talking about things not in the California law) then say how it should work and describe something close to the California law.
The age verification is coming from the Digital Age Assurance Act.
this act is pushed by the NGO 501c3 called Common Sense Media, their donors include Bezos, zuckerberg, and other rich people.
The same NGO also created a platform called Bandio that provides age verification services. How convenient.
Legislate restrictionist policy today that manufactures demand for age verification service, and then rollout the solution for $$$.
How convenient, muh free market capitalism.
Common sense media also earns $15 mln revenue from licensing its content rating technology.
It's not out of the ordinary for folks on HN to discuss the general subject of a topic and not the exact contents of TFA. The article tends to just be a catalyst for discussions.
It is kinda silly to read comments that do what you mention at the end (have a seemingly novel idea to fix the issue at hand and their solution is the one from TFA). That's just embarrassing.
But I feel like the rest of the discussions are fair game.
