I wish we could spend less (collective) time here on HN talking about/worrying about Elon Musk.

We're (allegedly) here for "anything that gratifies one's intellectual curiosity".

What SpaceX and/or Tesla are doing could certainly satisfy that, worrying about Musk himself certainly isn't.

Agreed; I mentioned Elon because the post made the reference quite explicit by saying "trillionaires", probably given the context Bezos or Gates would've been better examples though.
