I wish we lived in the timeline where the most reputable and market-leading age verification provider was PornHub, which would have a modestly dressed model check via video chat. I'd actually trust that more than the actual providers that exist in reality, and hey, if even 1% of the money goes to college tuition, great. Of course, if that was how this worked, the optics would kill most of these schemes before they were implemented.
As a parent, I'd like to point out that the threat I care about is not "my kid of age N talks to a sicko of age M, where M - N > P for some legislatively-prescribed value of P".
The threat is "my kid of age N talks to or can be observed by a sicko".
These age verification schemes do nothing to help against that. Also, the worst predators online are often the vendors providing "kid friendly" services.
On top of that, these laws are being pushed hardest by the worst of the most corrupt politicians on earth. Why would I install a webcam on my kid's machine because that group of people wants me to?!?
Maybe we should focus on prosecuting the backlog of stuff in the Epstein files pertaining to politicians pushing these age verification services, not let anyone (except parents) control how kids access stuff online.
