Re: ChatGPT is a data privacy nightmare, and we ought to be concerned.

It has no more privacy implications than a search engine. Headline is borderline clickbait in my opinion. Every "argument" against what ChatGPT is doing can and could have been said about any search engine.

I will bottom line it:
Either you did something and put your own information on the internet, and it was crawled. If you don't like this, then don't publish your info.
Or you did something, like get into the news, and the news was put on the internet, and it was crawled. If you don't like this, then take it up with the person who published it on the internet.

Ars, you are better than this.

...if it is discovered that google is training their AI on your personal unpublished data, well, that is a horse of a different color. I'm don't trust Google since their business model has always made normal users the product for their advertising customers. I'm more likely to trust Microsoft who has always been at the forefront of privacy and have great internal rules about managing and separating PII (personal identifiable information).
