Someone talks about Something today. Statement about how their position is incomplete. Somewhat self-deprecating statement of my position. Poorly-developed support of that position, with reference to personal experience. Question of applicability of the preceding two statements?
Exposition of the pros and cons of Someone's position, especially in the context of This guy and the other one. Then again, statement about the difficulty of having an informed opinion on the subject. Explanation of the technical details of the situation, with a relatively well-developed analogy. Overextension of the analogy to absurdity, to demonstrate its limits.
Call for more thought on the subject, or at least acknowledgement that the state of the art is still pretty bad. Personal reference.
Snappy four-word signoff.
