US tech tycoon Elon Musk said on Wednesday that he occasionally sleeps in the workplace and has a spot on a couch in a library on the seventh floor “that no one goes to” in a rare interview with BBC.

The American billionaire, known for his outbursts, discussed Twitter Spaces, which has more than three million members, with a UK media site.

About his tenure as owner of Twitter, Musk responded as follows: “It hasn’t been monotonous. That has certainly been a rollercoaster.”

Although Musk believed he made the correct decision in buying Twitter, the following few months had been “actually quite a tough position.”

He said that Twitter’s personnel had been drastically reduced and added that it had not been simple to reduce it from roughly 7,000 when he purchased the company to about 1,500.

According to media sources, since Musk’s $44 billion acquisition of Twitter, the company has been characterised by confusion and uncertainty. This is because many of the engineers responsible for resolving and avoiding service disruptions have been laid off.

According to internet watchdog group NetBlocks, Twitter experienced its sixth significant outage since the start of the year last week when a problem blocked thousands of users from accessing links.

Musk recognised some issues, such as recent outages, but claimed they were short-lived.

He claims that Twitter had to take extraordinary measures due to a $3 billion negative cash flow crisis, which included mass layoffs.

If everything goes according to plan, he added, “We might be cash-flow positive this quarter.” He also noted that the company’s user base is at an all-time high.

The billionaire, who also owns rocket manufacturer SpaceX and electronic car producer Tesla, claimed he has no one in mind to take over as Twitter’s CEO.

But he added that he would only sell the business to the “appropriate person.”
