I'm wondering if this whole 'buy twitter' idea is some sort of displacement activity from stressful problems in either spacex or tesla. I'm a fan of both companies but I know he drives them hard and takes lots of expansion risks/gambles with them (innovation is a gamble at the end of the day).

It reveals that everything he ever said about Mars, or about global climate catastrophe, was just so much posturing.

How?

Money is fungible. Dollars put into Twitter are, exactly, dollars not put into those other things.

Dollars speak louder than words. Musk can say anything, anytime. What he does with his money demonstrates what he believes.

Unless he thinks those dollars, turned via Twitter into leverage and influence, will have a payoff in the space space?

You must have seen how he tweets, no?
