Mark Zuckerberg has warned against trying to return to normality amid the coronavirus pandemic.
The 35-year-old billionaire - who is the co-founder of Facebook - has dampened down talk of reopening the US economy at this moment in time, suggesting it would be a bad idea for public health and the economy.
He said: "While there are massive societal costs from the current shelter-in-place restrictions, I worry that reopening certain places too quickly before infection rates have been reduced to very minimal levels will almost guarantee future outbreaks and worsen longer-term health and economic outcomes."
By contrast, Elon Musk has been outspoken about the lockdown in California.
The tech entrepreneur has described the government's policies as "fascist".
He recently wrote on Twitter: "To say that they cannot leave their house, and they will be arrested if they do, this is fascist. This is not democratic. This is not freedom. Give people back their goddamn freedom. (sic)"
Musk also suggested the lockdown is an infringement of American values.
He said: "Breaking people's freedoms in ways that are horrible and wrong is not why people came to America or built this country. (sic)"
