Having used AI a lot in previous blog posts I can now identify something which is AI generated very easily, and I am sure that search engines can do so too. In a blog post, Google said:
-----
Google's ranking systems aim to reward original, high-quality content that demonstrates qualities of what we call E-E-A-T: expertise, experience, authoritativeness, and trustworthiness. We share more about this in our How Search Works site.
Our focus on the quality of content, rather than how content is produced, is a useful guide that has helped us deliver reliable, high quality results to users for years.
For example, about 10 years ago, there were understandable concerns about a rise in mass-produced yet human-generated content. No one would have thought it reasonable for us to declare a ban on all human-generated content in response. Instead, it made more sense to improve our systems to reward quality content, as we did.
Focusing on rewarding quality content has been core to Google since we began. It continues today, including through our ranking systems designed to surface reliable information and our helpful content system. The helpful content system was introduced last year to better ensure those searching get content created primarily for people, rather than for search ranking purposes.

I think the keyword here is "original", and since most AI clients such as ChatGPT simply rip information from other sources, that originality can be disputed when something is AI generated.
And this is why I'm not using AI generated content on RTS HQ, with the aim to have every article "handwritten". The irony is that I've become so used to the structure of AI posts that AI checkers sometimes return a false positive on content I have research and written myself.
