Tesla (TSLA) CEO Elon Musk accidentally shared his phone number with his 16.7 million followers via his personal Twitter (TWTR) account. But he's typical a little more tactful when making intentional announcements on Twitter. 

And with his seemingly endless stream of ventures that includes SpaceX, The Boring Company and of course, Tesla, he never has a shortage of topics to talk about. 

We took a look at some of Musk's biggest social media moments: 

1. A First Look at the Hyperloop

Musk's Boring Company is taking a step to prove building inter-city high speed hyperloops is more than a pipe dream

2. His Fear of AI technology 

Musk has repeatedly stressed his belief that artificial intelligence will be the best...or the worst thing for humanity. His strong opinion has launched numerous debates, including one with Facebook (FB) CEO Mark Zuckerberg. 

3. A sneak peek of the first SpaceX Spacesuit

Musk founded SpaceX in 2002 to promote space exploration and build a less expensive rocket.

4. The Birth of the Boring Company

Now that the Boring Company has begun making headway, it's hard to believe it was once just a tweet. 

5. A plan to restore power to Puerto Rico

What began as a series of tweets sparked a conversation with Puerto Rico's governor and Tesla's involvement with the territory following destruction from Hurricane Maria.
