I judge Elon based on his track record and shit like the Hyperloop (does he not understand the concept of a subway train?)
I think you're confusing two of Musk extremely stupid stunts. The hyperloop is the vacuum train concept that is proven to not really be possible afaik, he "released" a white paper detailing the concept, they've been "working on it" for over a decade now.
I believe you're thinking off the dumb tunnels that the Boring Company built, which would be extremely embarrassing to call a "Hyperloop" as it's just some cars (with drivers!!!) driving at slow speed through tiny tunnels.
A genius at work huh
That said, the "liberal" hysteria about unregulated speech and whatnot is also straight up embarrassing.
In the grand scheme of things this does really matter though, shit like Twitter that is something that countries like China don't have, and there's a lot of power there. Who knows what Musk would do as CEO, and he really needs to remain good friends with China to keep Tesla afloat. It has been clear that the US government wants some/more control over these large tech companies (misinformation!!! lol ... yeah yeah, control over Twitter can mean more control over what people think in years, that is the power of the now and future) and Musk really is just a loose cannon.
