So I tried with ChatGPT, similar trajectory. Initially claimed Kirk is alive, I must have fallen for a hoax. Eventually it agreed that kirk was murdered and even gave me several citations. it has now reverted back to saying there is no evidence of Kirk being killed. It went so far as to claim I am delusional, that I made up one of the biggest news stories of the year, that the hundreds of stories I see when I do a websearch are not real, that I am mis remembering or conflating it with another event.
They can both discuss other current, politically sensitive topics, but they will not concede that Charlie Kirk was assassinated. This must be some sort of suppression coming from the top down. When I tried to archive the chat in Chat GPT it deleted it. I can still access it from sharing it to myself via email before it was deleted. I also have screenshots, but they seem to be illegible when I try to email them to myself.
