Every single thread where he's the topic, without exception, focuses at least in part on attempting to strip Musk of any accomplishment. He is allowed to have accomplished absolutely nothing. There must be zero redeeming value to his existence.
The extreme nature of the focused attacks on him today are fascinating to watch in terms of how angry, irrational mobs form on targets and attack until there's nothing left (and then they keep attacking, because some people are late to the party).
They attack his parenting.
They attack his business successes.
They attack his mental capabilities and rationality.
They attack his character.
They attack his family and background.
They lie about all of the above to whatever extent is necessary.
This goes on here, on Reddit, Twitter, wherever a discussion about Musk arises. The only difference between HN and Reddit on this topic is that HN is slightly more highbrow, although the same general attacks get repeated here as they do on Reddit.
Someone on Reddit yesterday was proclaiming that he "attached" himself to the SpaceX success and deserved zero credit for it. That rather nicely encompasses what's going on.
It's one of the biggest shit shows in the history of the Internet. It's embarrassing - as a human - to watch so many people desperately rolling around in the muck to participate.
