I agree with your observations. Musk has his idiosyncrasies as all billionairs. However he's done a great job of remaining relatable. Look at those emotionally retarded sociopaths like Gates, Zuckerberg, and Bezos, repulsive at best.
Zelensky does a lot of blow, and that's not just hearsay, he's touted openly that he loves the stuff, and after a while it effects your judgment, i know. He's acting like a spoiled child, probably from all the media attention. Remember the guy was a comic and an actor prior to this.
Musk is a man of his own making, Zelensky was installed as a puppet, cast for the role. He actually may not be the one in charge of this dumpster fire clown show.
