Meta's has been listening to some concerns after all especially now after some pressure.
These changes very well could help parents moderate their teens. Meta's head of product says these changes address particular 3 concerns in an Npr interview.
Will this be the end of the complaints and concerns geared towards Instagram, probably not.
I'm personally on the fence about this type of stuff. On one hand, yes I 100% agree about actually keeping kids safer online (not like the politicians "Think of the kids!" type of "safety"). On the other I don't want anyone to have to give up privacy by having to confirm their age by sending some form of verification, whether that picture/video of ID with birth date on it or having an AI that will inevitably get so many false positives judge you, just to access a service online.
Anything to prevent getting my i.d in a database, i would actually be ok with using an ai to verify my age by my appearance if it really came down to it and I had to choose legally some form of age verification.
