Feel free to skip this comment. Sometimes I write comments for HN and then delete them. I almost deleted this one (which means I probably should have). This is what's in my head.

Why didn't Tesla buy Twitter? Why could Tesla start spending massive amounts of money on Twitter Ads if it couldn't buy it?
SolarCity was in a related field, which was at least a fig leaf or minimal justification. There's no real justification to buy Twitter or buy ad space on Twitter.
Elon is not actually the god emperor of Tesla. He's been able to sell all of his decisions as improving the future of Tesla (and thus humanity). Of course I could be completely wrong here; I don't have a crystal ball.

I think about how we might get to a post-scarcity society, and what post-scarcity means. People like Gene Roddenberry have done a great job portraying this future, but not how we get there.
Much of our political discourse is between people who disagree about whether or not we are living in a time of scarcity or post-scarcity. Many people in the city live in the low-scarcity mindset. Many people in the country live in a scarcity mindset. This isn't determinative, it's relative. Just being one place or the other does not dictate how you view the world, but it is indicative.
We don't talk about scarcity directly in political speech. It's a deep assumption about the world. It's so deep you may not have even realized that you had taken a side before now.
Are taxes and economic activity a zero-sum game? Obviously the other side is wrong, why would you even entertain the question?

Why the fuck did I bring up Star Trek and post-scarcity? Because Twitter is a place where fights happen. I'm very happy that people are sending tweets instead of bombs, but we have to continue advancing our level of discourse, and I'm not at all convinced that online public speech is the way to do that; I'm especially not convinced that we can do that in short form; and I'm especially especially convinced that the process of advancing the discourse will not be funded by ads.
