That of course was a story two days ago on Business Insider, that the NY Post ran, that Gurman picked up on... etc.
The claim is an old one, such as this from last June:
Why doesn’t Tim Cook wear Vision Pro in public? To avoid becoming a meme!
I'm not sure it is really significant, though. The device has clearly been through many design revisions, with the latest version looking different than the one in the videos created just a few months before.
After it is launched, then if Cook et. al. are not seen wearing one the argument will be stronger.
I don't think it looks "dumb", any more than any other type of human headdress.
However, I do think Apple should have gone with some designer labels and have optional designer-specific looks.
