One could make the argument that it has, via political changes. DOGE, for instance, who's cuts have been linked to hundreds of thousands of deaths, would have been very unlikely without social media.
Just in case you're too young to remember, nutjob politicians with stupid ideas long predate social media.
What, because of the doge meme?
Because of the misinformation that led to DOGE cutting funding on programs that saved a lot of lives, but cost almost nothing. People elected the present government based on the lie that the budget could be balanced by cutting things like foreign aid and the arts, but in fact those things are a rounding error in the overall budget.
