Musk has a ‘super app’ plan for Twitter. It’s super vague 

It’s worth remembering Elon Musk’s grand visions don’t always work out the way he appears to expect. His promised fleet of robotaxis remains about as far from reality as the metaverse.

Elon Musk has a penchant for the letter “X.” He calls his son with the singer Grimes, whose actual name is a collection of letters and symbols, “X.” 

He named the company he created to buy Twitter “X Holdings.” His rocket company is, naturally, SpaceX.
