In January 2020, shortly before the world shut down, Jack Dorsey invited a special guest to speak at Twitter’s companywide offsite in Houston: his favorite tweeter, Elon Musk.

The short FaceTime conversation, which was projected onto a giant video screen as thousands of employees looked on, was oddly foreshadowing. Dorsey jokingly asked Musk if he wanted to run Twitter, and Musk complained that he encountered too many bots on the service. Dorsey ended the discussion with effusive praise.
