In 2021 the WEF launched the Global Coalition for Digital "Safety" [1] it includes Google, Meta, Interpol, and any neoliberal goul you can imagine. The push for universal digital identity cards is much older ofc. like (eIDAS 2.0) in the EU [2]
Meta and TikTok already developed AI based age estimation tools into their platforms, then lobby to have have laws passed accordingly. See this from 2023 [3]
There are also companies that offer these sorts of services pushing legislation, how else are they gonna justify their hundreds of millions in valuation? (Like yoti [4] or Clearview ai [5])
