For example, Elon Musk was smart enough to do some things … then he crashed and burned with Twitter because it’s about people and politics. He could not have done a worse job, despite being “smart.”
That is, if you do not subscribe to one of the various theories that him sinking Twitter was intentional. The most popular ones I've come across are "Musk wants revenge for Twitter turning his daughter trans", "Saudi-Arabia wants to get rid of Twitter as a trusted-ish network/platform to prevent another Arab Spring" and "Musk wants to cozy up to a potential next Republican presidency".
Personally, I think all three have merits - because otherwise, why didn't the Saudis and other financiers go and pull an Altman on Musk? It's not Musk's personal money he's burning on Twitter, it's to a large degrees other people's money.
Of the $46 Billion Twitter deal ($44 equity + $2 debt buyout), it was:
* $13 Billion Loans (bank funded)
* $33 Billion Equity -- of this, ~$9 Billion was estimated to be investors (including Musk, Saudis, Larry Ellison, etc. etc.)
So its about 30% other investors and 70% Elon Musk money.
