Context is everything.

"Combined views of the conversation with @realDonaldTrump and subsequent discussion by other accounts now ~1 billion," Musk posted on his social media platform X early Tuesday morning following the interview.

The message followed a previous post outlining that, "Between 7:47 PM and 10:47 PM ET, President Donald Trump's Space post received 73 million views. During the same period, there were 4 million posts about Elon Musk and President Trump's conversation on 𝕏, generating a total of 998 million views."

A view may be 1 person, or a family watching, or a bar full of people. If I comment on it, after having watched it - that's 2 views. If my wife replies to 6 people commenting on the interview - that's 7 interactions, or views. If we access the interview, and skip through it for key parts - that's yet another view. It's not the same as 1/8th of the world population. It's a metric as to how many times the same content was addressed.
