The new title at Block is Block Head, not CEO. This is not a joke. The new title came into effect on 4-20, after the company filed an 8-K with the SEC announcing the change.
The job of Block's head and chairperson will remain the same despite the new title.
According to the filing, the change happened at Dorsey's request. He may have seen his face on the official website of Leadership, which I have used as the image at the top of this post. As of press time, that page still lists his title as CEO.
In lieu of CEO, Musk crowned himself the Technoking ofTesla in 2021.
