You're not looking at this with the right perspective. Hyperloop, EV's, solar panels, batteries, huge tunnels, reusable rockets. What's the common thread here?
This is obviously all the technology that Elon thinks is necessary to colonize Mars, and in each case he's doing the best he can to develop it on Earth. However its usefulness on Earth is a secondary concern.
Where does Twitter fit into being useful technology with which to colonize Mars?
Think the fact that the engineering problems Musk demonstrated some aptitude for finding solutions to were also vaguely related to his stated aspiration to colonise other planets actually perfectly fits the armchair speculation that Twitter is just an addictive distraction from hard science which he's pursuing out of sheer hubris, not because of any grand vision but because he said he could do better than the people in charge and people liked his posts
Simply put, Twitter is a tool of immense political influence, and Musk has realized he needs to regime change the US and kill the "Woke mind virus" to ensure his Mars plans happen.
I'm going to go out on a limb and suggest his Mars plans would be better served by a few well-placed lobbyists for public-private partnerships with NASA than by spending $44bn on making the platform he previously got to vice-signal on for free less popular...
It was a tool of political influence before he killed it and the journalists who would cover and amplify political figures left because it is no longer interesting.
But, then again, "woke mind virus"--the cope, it's real.
Yeah, he's pretty much the most trustworthy person on the planet and has never lied to serve his own ends. I mean, I guess there's still you that's the weak link in that chain of trust, but otherwise certainly if he said it it must be true.
