We are trapped in a meme.
Unless your spoken English isn’t very good, it’s quite clear there is no “s” sound in the second half.
Say “space sex” out loud and yes you’ll hear two distinct ‘s’ sounds. Not at all the same as “space ex”.
Of course it's not the exact same sound, but it's bloody similar and it's a throwaway tongue-in-cheek comment from GP. Are you and the sibling comment robots that don't get word play?
To be clear, I'm willing to agree that it's a funny mispronunciation, but am unwilling to accept that this particular naming was an intentional juvenile joke by Musk. It's widely known he's a fan of the letter X, and I believe that fully explains "SpaceX".
But maybe possible it’s just all about the letter X for him?
Also, to clarify, I don’t dislike the guy. Nor do I dislike his naming. Just pointing out what I thought was the obvious.
fwiw, I don't like Elon and I think this whole thread is kinda distracting to actual points about Elon that don't need Olympic size hurdles to understand.
