Google has a guidelines in its webmaster guidelines against automatically generated content but that guideline might change as machines and AI get better at producing not just understandable but useful content for humans. John Mueller of Google said thinking into the future, he can see this guideline changing with that. But for now, machine written content is not okay.
Via DeepCrawl on Twitter, John Mueller of Google said at the 53:05 mark into a video hangout that maybe a few years "down the road, I could imagine that that happens," where Google allows such machine written content. He said "So with that in mind, I think at some point in the future, we will have to revisit this guideline and find a way to make it a little bit more granular and that it kind of differentiates between these totally spammy uses of auto-generated content and the actually pretty useful uses of automatically generated content."
This is not old fashioned content stitching or really spammy stuff, this is content that is not just "actually pretty understandable" but "actually pretty useful" John said. We covered this topic a couple years ago and Google was already iffy on the topic, so I suspect this will happen soon enough.
