• Musk said in the tweet the he'll transition to being the company's "exec chair & CTO, overseeing product, software & sysops."

Flashback: Shortly after taking over last fall, Musk said he planned on eventually replacing himself has head of the company, and in December ran a poll that ultimately had a majority of voters saying he should step down.

The intrigue: Musk has long expressed his dislike of the CEO title, arguing it's "made up" and "doesn't mean anything."

• His announcement also noted this person will lead "X/Twitter," the former likely a reference to the new legal entity that recently absorbed Twitter (and relocated its corporate domicile from Delaware to Nevada), as well as his aspirations to turn Twitter into a "super app."
