Billionaire entrepreneur Elon Musk has taken a shot at 'woke' culture in a tweet imagining a world consumed by social justice demands as an exciting new video game.

'Woketopia. Battle for the Moral High Ground in this new game!' the Tesla CEO wrote in a tweet on Saturday.

Musk did not elaborate, and it was not immediately clear what had prompted the remark.

It came soon after a report that hundreds of employees at Tesla's plant in California contracted COVID-19 after Musk urged them to return to work amid the coronavirus pandemic. 

Musk has also faced criticism for his skepticism of coronavirus vaccines, including concerns he has expressed about potential side effects.

'Woketopia,' the concept of a woke utopia dominated by social justice demands, is a phrase that has also been used by Don Trump Jr and commentator Bill Maher, among others.

Musk's proposal for a 'Woketopia' video game garnered mixed reactions from his followers.

Computer scientist Paul Graham responded, 'That would actually be an interesting game to design.' But game designer Tyler Galilee replied derisively, 'Okay Boomer.'

In another odd tweet on Sunday, Musk wrote: 'I love music. It makes my heart sing.'

Musk has long shown an interest in video games, and once credited computer games for first interesting him in programming.
