Also I think AI at least in its current LLM form may be a force against polarisation. Like if you go on X/twitter and type "Biden" or "Biden Crooked" in the "Explore" thing in the side menu you get loads of abusive stuff including the president slagging him off. Type into "Grok" about those it says Biden was a decent bloke and more "there is no conclusive evidence that Joe Biden personally committed criminal acts, accepted bribes, or abused his office for family gain"

I mention Grok because being owned by a right leaning billionaire you'd think it'd be one of the first to go.
