Elon Musk, the CEO of Tesla and SpaceX, is known for being very outspoken on social media for good and bad.

The quirky entrepreneur recently tweeted a strange comment that left everyone scratching their heads. Musk said “Twitter is the Dark Souls of social media”, called Reddit the equivalent of Bloodborne, and finally, proclaimed Instagram the Zelda of social media.

Twitter is Dark Souls of social media. Reddit is Bloodborne. Insta is Zelda.

No one knows what his comments really mean, especially when calling Instagram the Zelda of social media. Hopefully he’ll shed some light on it soon.
