Doesn&#x27;t seem so &quot;fool proof&quot; to me as where the inevitable media spin will take it. Then, how do you know &quot;where&quot; to steer weights? &quot;Safe&quot; has no agreed upon definition</p><p><a href="https://hackerpaper.kaipfister.de/p/2511.08425/">Paper and discussion history</a>.
