It's been seven years since Elon Musk sent a Tesla Roadster into space, so why did he do it and where is it now?

For years, Elon Musk has talked about Dojo — the AI supercomputer that will be the cornerstone of Tesla’s AI ambitions. It’s important enough to Musk that in July 2024, he said the company’s AI team would “ double down ” on Dojo in the lead-up to Tesla’s robotaxi reveal, which happened in October.

Musk, who also runs SpaceX and a number of other companies, has been known to make big often exaggerated promises. For example, he once called the Hyperloop, which was never built, the "fifth mode of transport" and famously promised to take Tesla private in a Twitter post, saying he had secured financing that he didn't have.
