I doubt it. I've worked in a couple different social media companies and default age system is ml guessing unless you do something extreme like this. That gives you reasonable accuracy, but still very noticeable error that's a lot worse than id requirements. It's fairly hard to have confident age especially when a very high percent of people lie about there age if you just ask directly. I remember hearing a number like half of people underage just lie at work although unsure how serious that stat was. There were engineers that did spend projects on better age modeling as other ways just seemed unviable. If you make a legal requirement well enjoy id requirements. The main path I can see around this is if the government/some company became accepted standard place for basic profile information. But that's just another id except a digital one. You can probably make a digital id system with good way of specifying which fields you grant to another company. The actual digital id when created will still need a physical id/government check though.
