Elon's focus is to earn money and control power.
I don't know about money (he probably wants that too), but I see him as someone who wants more control.
I have a feeling that Elon is just throwing out a bunch of ideas to see what works.
I don't think so... He is just socially awkward, and that makes his plans for Twitter harder to implement.
And yeah, I believe everything was part of a plan. Maybe not the rate-limiting thing. That was a response to ChatGPT and the like using the content on Twitter to grow their knowledge base, just like what Reddit did (except they want to be paid).
