So from now on, do we present our credentials and cvs before commenting to any extent in public? No. The whole point about science is that anyone at all should be able to criticize any piece of work on the basis of the facts.<p>Let&#x27;s suppose the criticism is rubbish. All to the good. That will emerge and so will salient criticism, if it exists, that may have escaped the &#x27;credentialized&#x27; scientists.<p>Only my impression of course but reading a few entries in Shtetl-Optimized, I would have thought that Aaronson would certainly appreciate and argue for or against any pertinent comments that some unknown Joe Doe might offer.
