I cannot remember exactly where Elon said' first in last out'. I think it was a conference call. Either way I do remeber listening to those words, and I had zero doubt what it meant at the time. No nuances necessary.
If Elon is indeed selling shares to purchase Twitter, then this is a fundamental change in his stance, which one should incorporate into their overall investment analysis. It might not change your concuslion, but when variables change, one probably should pay attention.
On another note, I was always taught do not count on something until it is in your hand. So the whole 'funding secured' debacle, I have yet to see anything concrete that would of indicated that. No doubt there were discussions, and intentions probably verbalized, but to say 'secured' when there is zero in writing to myself is a poor choice for a CEO (at the time) to make. Elon is impulsive. He demonstartes this a lot. He also obviously dislikes dishnoesty. So in my humble opinion, sometimes Elon does something, impulsive, wants to stay true to himself, so then figures out how to do that. Fifty per cent or more of people with Autism, have ADHD, the exective function disorder that can make it hard to regualte your attention. Hence you can hyperfocus, and get really, really into something. Like maybe rockets. Or electric cars or whatever it is. Impulsvive actions, like maybe 'fat-shaming' someone also can be part of ADHD.
