No different from what people said about Wikipedia when it was new (and justifiably so). How should one deal with people who trust Wikipedia?

Studies showed wikipedia was about as accurate as encyclopedias, so that fear was already debunked. That is not true for LLM, LLM are much less accurate than encyclopedias still since there is no limit to how far you can push them while encyclopedias and wikipedia stay in domains where they are still mostly accurate.

Ask the nice AI to cite sources, and then have another AI fact check their sources. The agentic era is interesting.
