Before the Cambridge Analytica story had broken. Before Facebook's acknowledgement that its platform had been used to help incite ethnic cleansing in Myanmar. Before the WhatsApp lynchings in India. Before QAnon and the Proud Boys - Mark Zuckerberg had the world at his feet.

So much so in fact, that at the start of 2017 he decided to tour America.

In a Facebook post, he said he wished to "talk to more people about how they're living, working and thinking about the future".

His goal was to speak to people in all 50 states - to get out and engage with real Americans.

It was seen by some as the start of a possible 2020 presidential bid - something he always denied.

His potential candidacy was seriously debated in the press - he had money, drive, and power.

This week, Joe Biden took the job that many believe Mark Zuckerberg secretly craves, or at least craved. And in doing so, he completed a reverse metamorphosis for Zuckerberg. A butterfly no longer, he finds himself alienated politically.
