I understand calling him pompous, or an ass, and he had that period where he basically was a part of gamergate for a minute (maybe he still believes those kinds of things, I'm not in his head). He definitely will take a "debunking" that should take two minutes of math, and spends 20 minutes basically reveling in "just how wrong" the supposed Bad Man is.

But when has he been wrong, in a way that would cause you to call his credibility "dubious"? When has he called out an Infinite energy machine, or a "pull water out of the air in a desert" machine, or an Elon project, and been wrong?

Well, IIRC, he said there was no economic or technical advantage to reusing rockets, and predicted the demise of SpaceX. That Tesla would never produce a semi-truck, then when it did he significantly misrepresented the details so he could "bust" it. And probably others. I try not to waste much brain space storing his BS.
