It sure doesn’t look like it. The announcement was strange and anti-climatic, and it started making excuses for itself immediately “Grok is still a very early beta product – the best we could do with 2 months of training”. It has the Elon stink all over it.
He doesn't have to be because he doesn't make everything about himself at the companies he runs. You seem to have a pretty skewed idea of what a CEO is for.
