Why is that convincing? You'd have to have inside knowledge of Musk's day to day value add in a way you were certain wasn't created for PR purposes.

On top of that, you'd have to treat his Twitter account as anomalous and not indicative of his day to day work because of ...some reason?

He's just a figurehead. SpaceX does best when Musk is absent and Shotwell is in charge. Notably, every major SpaceX failure has happened when Musk decided to come back to the facilities and meddle in the engineers' work.

i've never trusted him ever since he promoted Leap Motion as some great piece of tech. and his notion that two cheap ass cameras should be sufficient to get self driving up to par with human drivers really sealed the deal. he's a fucking idiot. maybe he gets coached by people who actually know what's going on when he does pr shit.
