Interesting reading, but the descriptions are so general that I don't see this having any practical value for SEO.

When we develop new AI systems, our legacy algorithms and systems don’t just get shelved away. In fact, Search runs on hundreds of algorithms and machine learning models, and we’re able to improve it when our systems — new and old — can play well together. Each algorithm and model has a specialized role, and they trigger at different times and in distinct combinations to help deliver the most helpful results. And some of our more advanced systems play a more prominent role than others.

When something is this complex, it could be hard to pinpoint the cause of any problems that might arise.
