Debunking bullshit inherently takes more effort than generating bullshit, so the human factor is normally your big force multiplier. Does this person seem trustworthy? What else have they done, who have they worked with, what hidden motivations or biases might they have, are their vibes /off/ to your acute social monkey senses?

However with AI anyone can generate absurd torrential flows of bullshit at a rate where, with your finite human time and energy, the only winning move is to reject out of hand any piece of media that you can sniff out as AI. It's a solution that's imperfect, but workable, when you're swimming through a sea of slop.
