It's fair to say Elon Musk has a lot on his plate at the moment.
The world's richest man has taken out $US20 billion (more than $30 billion) in loans to buy Twitter — a relatively unprofitable social media website many have idealised as being a "global town square".
The interest bill for Twitter alone is expected to be about $US1.5 billion per year, according reports by the New York Times, Bloomberg and the Financial Times.
