I haven't read this paper, but... What separates a good paper from a blog post is the attention it devotes to second and third order consequences, its discussion and dismissal of likely counter-arguments, and the author's framing of the new idea in the context of existing literature.

These are the hallmarks of careful analysis that are generally lacking in hot-take blog posts.
