Honestly, I don't think these guys are in competition with each other for the title of world's richest person--especially Warren Buffett. I am kind of surprised that Elon Musk is worth that much, but then again I don't really know much about him (yeah, I don't follow the news all that much).
Regarding the retaining of the title: If Musk is worth $23 billion, I don't think he'll have much trouble remaining the richest person on earth. ~
Man, I have to admit you scared me.

Of course, it was a mistype from your end, you just missed a zero, because this is the latest estimation of Musk's worth

but for a fraction of a second, since I don't follow such news too, I was thinking that I didn't know his worth even approximately.
Then I started wondering was mentioning "$23 billion" by another member after your post a mistype too?
And then I checked the OP, and finally it all made sense

One zero was missed in the screenshot!
