I’m not sure it’s social media so much as the smartphones. It’s been surprising to me watching my parents become slightly senile in a way that seems related to phones – much less ability to cope when the phones aren’t quite working and a lack of the habits I see in my own generation (eg one should obviously try to avoid having a phone out at the dinner table).

I don’t think I agree with your take around religion or ‘evil’. (Imo two big advantages of religion we are currently or will soon be wanting for society are firstly the social/community component and secondly the idea that one can lead a worthy and fulfilling life through acting virtuously and faithfully, rather than through the worth implied by educational or career achievements, which are often a rough proxy for certain kinds of intelligence, that are neither evenly distributed across the population nor easily changed, and which may become unimportant as machines outcompete us there)
