Yeah, except we'll have thousands of nutjobs running around. Each running their own instance of your New Testament LLM. Each thoroughly convinced they are the messenger of the new digital messiah. According to the text of the Bible, many people walked away from their lives and abandoned everything to follow Him. Considering what we observe in modern cults, that doesn't seem an unlikely historical reality.

An LLM trained on the words of Jesus won't just tell people to live good lives. It will be telling people, "give everything up and follow Me (the computer.) And if it was a good enough LLM, it would be pretty persuasive for good number of people. The one saving grace is that JesusGPT isn't going to be healing the sick, walking on water, or raising the dead any time soon. But words alone can be quite dangerous.
