I was a big Elon Musk fanboy for what he was able to accomplish on both Tesla and SpaceX. I had the impression that he was very genuine and really wanted to "save humanity".
I ignored the crazy things he said on twitter. I think his accomplishments overshadowed his less favorable behavior.
But after his tweets about Ukraine, it really started to dawn on me that his "save humanity" was not really save humanity, but just a really good sales pitch. He fooled me, I confess.
Right now, I see him as a very successful businessman. But if he can choose between making money or "doing the right thing", I think it's clear by now that he would go for the money (like jump into bed with Russia or China in a heartbeat, as long as it delivers the extra buck).
Buying Twitter seems like a really bad idea, for both society and his pocket. I think we're seeing "Haughtiness comes before the fall" (I didn't use 'pride' because in Dutch this expression seems better)
