Is it really that much worse today? When I was a kid, my great aunt died of skin cancer. She was a Christian Scientist and rejected medical treatment in favour of prayer.
As a teenager, I remember being annoyed that the newspapers had positive articles on the rejuvenating properties of nonsense like cupping and reiki. At least a few of my friends' parents had healing crystals.
People have always believed in whatever nonsense they want to believe.
It feels like the friction to get un-science has been completely removed now. Before you had to get lagged content and physically fetch it somehow. Now you can have it in the palm of your hands 24-7 with the bonus of the content being designed to enrage you to get you sucked in.
LLMs and the internet both make it easier for us to access more information, which also means we can reach dumber conclusions quicker. It does go both ways though.
