Frankly, I do not rule out that these AI detector tools show Theymos or Satoshi as having plagiarism content/writing from artificial intelligence. I think that most of these detector tools, in my opinion, do not provide any correct or close to accurate results.
Right, there can be false positives, but if you'll try to go through big enough amount of posts on this forum with several most accurate AI detectors, you'll find out that nearly all posts are detected as written by human, 99,9% of all recent posts. It can also be false detected, because some little edited AI written text can be detected as human written, but well, not the hugest problem.
So when you point that AI detectors are not a 100% guarantee, we know that already. But if you have a bunch of posts in a row which are detected by several best AI detectors as AI written, it will be highly unlikely that it is just a coincidence.
And as for this exact case: how many human beings have a "knowledge cutoff in September 2021"?
It is accurate to say that Daniel Ricciardo currently competes for McLaren and not AlphaTauri. For the 2021 and 2022 seasons, Ricciardo is under contract with McLaren as of my knowledge cutoff in September 2021. Future changes to a driver's team are speculative and subject to a variety of conditions, including team decisions and contractual commitments. Which team Ricciardo will eventually join is hard to foresee.
