Elon Musk has took a cheeky swipe at fellow billionaire Jeff Bezos after it was reported the Amazon boss had acquired a self-driving taxi company.
According to the Financial Times, Amazon acquired the self-driving company Zoox for more than $1.2bn (£960m)
Sharing a link to the article, Musk tweeted that Jeff Bezos is a copycat:
Billionaire banter, eh?
It's been a very good year for both Musk and Bezos who have seen their wealth sky-rocket this year - with the SpaceX boss seeing his fortune increase by 55 percent since January and Bezos also seeing a sharp increase.
According to an article in Bloomberg from earlier this month, Musk is now worth $43.1 billion (£34bn) and is the billionaire whose fortune has grown by the highest percentage so far this year, but others have accumulated a greater amount of cash.
While Bezos' wealth grew by $33.5 billion (£26.4bn) in the same time, an increase of 29.1 percent.His total fortune stands at $148 billion (£117bn), according to Bloomberg.
Musk has had a busy year, launching his SpaceX's Falcon 9 rocket carrying NASA astronauts Douglas Hurley and Robert Behnken to the International Space Station in May.
SpaceX made history by becoming the first ever private company to send NASA astronauts into space - the mission is also the first time US astronauts have been sent into orbit from US soil since the Space Shuttle was retired nine years ago.
Following on from that, SpaceX sent up its eighth group of Starlink satellites, taking the total to around 500. Musk hopes to send 800.
Away from his SpaceX work, Musk has also revealed that Tesla is working on a battery that will last for a million miles for the Model 3 sedan later this year or early next.
Tesla hope that the new battery will bring down the cost of electric cars. Dan Ives and Strecker Backe from investment firm Wedbush Securities explained to Business Insider: "In our opinion this battery technology will be very advanced, potentially last for decades, withstand all types of weather/terrain, and be another major milestone for the Tesla ecosystem.
"In theory, this battery will support an electric vehicle for 1 million miles and be a major step forward when competing vs. traditional gasoline-powered automotive competitors."
Oh and he's also had a baby with his girlfriend Grimes - real name Claire Elise Boucher - and yet he still manages to find time to take the p*** out of Bezos online. Incredible.
