Amid the millions of posts about Musk becoming a trillionaire, that's the only interesting perspective.
He is a paper trillionaire. Now, I'm not delusional; Musk has created real wealth, but if we are being generous, about 80% of his wealth is based on the speculative future earnings of Tesla and SpaceX.
If those earnings don't materialize, Musk will not be known as the first trillionaire. He will be known as the first guy who wiped out several trillion dollars in shareholder value.
Something to keep in mind.
With the SpaceX IPO
@elonmusk is the first person to surpass J.D. Rockefeller as the richest private citizen ever. However, adjusted for over 100 years of inflation, Rockefeller earned about $2 billion per year in real income. Musk earns nothing. What a difference a bubble makes.
