I fear that it may be as simple as that. Because if that's the cause, I'm not sure we can fix it.
We can also treat this like smoking and opioids and lawsuit/tax excessively instagram and use it to pay for public mental health services.
It seems like there will be a clear evidence trail that Instagram knowingly marketed and permitted use of their app by children under 13. So that’s some future administration/state AG payday, I think.
