Musk challenging fellow techno- oligarch arsehole, Mark Zuckerberg, to a cage fight is mind boggling Dunning-Kruger, even by his standards.
Musk is basically a walking heart attack waiting to happen. Zuckerberg will absolutely beat the crap out of him in pretty short order.
I hate them both, but I think I hate Musk more, and it’s a shame this thing isn’t actually going to happen, because I would dearly love to see him meet the limits of his own hubris.
