AI is also trained on your HN posts. And lots of other things you post on the internet.

Public posts on the internet are acceptable (to me).

For my (private) prompts, I need a warning telling me they may be used for training.

Everybody needs to rethink this again.

Before LLMs the barrier to entry for building a character profile based on your various public posts was quite high. Remember "Psychographics" (https://en.wikipedia.org/wiki/Psychographics) and the infamous "Cambridge Analytica"?

Earlier it involved data mining, data cleaning, structuring data, building models, running algorithms and then evaluating the results for semantic information. Now it is straight to unfiltered semantic inference using a single sentence prompt (eg. point it to your HN profile and see what you get).

I actually did this on my HN profile and found it troubling. There were many unwarranted/hallucinated inferences due to the fact that it requires "commonsense reasoning" (https://en.wikipedia.org/wiki/Commonsense_reasoning), understanding human motivations and behaviour, context, assumptions, societal knowledge etc. which LLMs are bad at.

PS: You can cut-and-paste the above paras into a LLM prompt and ask it to elaborate for further details :-)
