So what good are these tools? Do they have any value whatsoever?
Objectively, it would seem the answer is no.
It seems to me that the limitations of this particular tool make it suitable only in cases where it doesn't matter if the result is wrong and dangerous as long as it's convincing. This seems to be exclusively various forms of forgery and fraud, e.g. spam, phishing, cheating on homework, falsifying research data, lying about current events, etc.
How do you fix that, when the process is literally "we throw an illegible blob at it and data comes out"? This is not even GIGO, this is "anything in, synthetic garbage out"
You gotta watch for that for sure but no that's not a issue we worry about anymore, at least not for how we're using it for here. The text that's being extracted from is not a "BLOB". It's plain text at that point and of a certain, expected kind so that makes it easier. In general, the more isolated and specific the use case, the bigger the chances of the whole thing working end to end. Open ended chat is just a disaster. Operating on a narrow set of expectations. Much more successful.
