  Upon closer reading, he explains it somewhat.

The author of the article is a nameless collective, not an individual. They explain it, but there is no "he" to ascribe the explanation to. We do not know the names of the authors.

I got this from twitter, where Elon Musk writes stuff like "Writing post now with details." and "Will get back to Autopilot update blog tomorrow." So I assumed he's authored the thing.

Annoying you are being downvoted. You are entirely correct, and it is worthwhile to fight against the nonsensical notion that Elon === Tesla.

For what it's worth, there is some strong evidence that Elon penned this post himself - not that it is clear from the post itself.

I was already aware of these tweets, but that doesn’t mean he wrote it all himself, just that he is involved in it. The fact is, the blog post has a byline and the byline does not mention Elon Musk or any individual person's name.
