An update to Google’s privacy policy suggests that the entire public internet is fair game for it’s AI projects. If Google can read your words, assume they belong to the company now, and expect that they’re nesting somewhere in the bowels of a chatbot.
Nothing especially new. I’m surprised it has taken this long to decide to use it for AI. At the same time, I hope they have a team ready to deal with all the copyright claims. If youtube was a minefield, AI will be. They’re stealing IP directly and recycling it. If Google becomes AI, then Google will make itself obsolete. We use Google to search for answers by others, not to be force-fed a single answer.
I think it might be really hard to do that. Looking at a picture you can see and pinpoint different styles quite easily. Writing styles don’t differ that much. There are some authors that stand out like Terry Pratchett, but I don’t think the average Joe Autho’ has a chance to get anything out of that. On the other hand may be, you can get some money out of your scientific papers. They should be quite unique. 
I had already assumed that my public posts could be read. That’s kind of the whole point of shouting into the void.
It’s similar to art. Nobody displays their art in a public gallery without the expectation that their art will be viewed.
They’re going to collect a lot of worthless data in the process. They will need to fine tune their “signal-to-noise” algorithms and machine learning.
Is anybody surprised by this!?
Now that someone else has got away with doing this Google can. They scraped it to improve search, now they scraped for AI. Iterative change.
