I think Musk's luck is running out, he's been too political this past year and he seems to also have run out of geek "street cred". Remember youtubers visiting (whatever the Tesla trade show was called) were more perplexed than impressed with what has been shown. Similar sentiment seen across trade shows (like CES) where everything was AI and no one seemed to ask themselves "why are we putting AI in this?". The answer, of course, for startups and stock listed companies, to make themselves more valuable on paper.
Investors would probably be aware of that if they run any kind of sentiment analysis on online social media content. And at the same time there's some pull-out from tech stock. So maybe some are starting to realise that things are too shaky for their risk profile?
If only some billionaires (trillionaires?) could strike a better balance between successful and human. Especially since most wealth is actually wealth transfer from the poor and from taxpayer coffers to the rich.
