Let he who has to deal with that friend who constantly sends blatantly false Xits to them throw the first stone. Honestly I feel like every social media post that makes a factual representation should come with a big flashing warning "THIS IS ALMOST CERTAINLY FALSE, LOOK IT UP BEFORE YOU REPEAT IT YOU DUMMY!"
And I'm only like 10% joking. Given the success of language models it should be moderately trivial to train one to recognize when a factual statement is made and apply the above warning. It's not even the children and teens I'm worried about. The people who seem to have the most trouble handling this are the adults.
