I've seen a lot of talk about the chat bot, but not played with it myself. I have looked at the image one and it can be handy to generate a new image for a post. The software is getting better at some form of understanding what people write, but what does it actually know? It will keep improving, but could it ever be considered aware? That would create all sorts of issues.
There will no doubt be other developers working on detecting machine generated content.
Are these the 'interesting times' they talked about?
