Misleading headline - but after a few para's, the article pretty much admits that Musk & Co.'s actual "AI" goals are keeping their giant egos on top of the white-hot hype heap, and keeping their $billions flowing. Either credibly defining intelligence, or focusing on building something that qualifies, would run contrary to those goals.
The Saudi investors who lost a lot of money on X still believe in Musk's "AI" efforts, at least in public (see Tucker Carlson interview with one of the princes). So it's better to keep up the hype and sell them additional GPU data centers.
