From the article:
This chatbot experiment reveals that, contrary to popular belief, many conspiracy thinkers aren’t ‘too far gone’ to reconsider their convictions and change their minds.
I think those people might not, but I was once a “conspiracy nut,” had a circle of friends who were as well, and know that for a lot of those kinds of people YouTube is the majority of the “research” they do. For those people I think this could work as long as it’s not hallucinating and can point to proper sources.
