I have now read all of the points in the mitigations section. Just like the slides, the commentaries to the mitigations willingly assert uselessness and imply a sense of absolute insecurity, but without specific or even general examples.

So I'm looking forward to your careful explanation of how insecure the whole thing is and how easily it can be dismantled. Because I really want and need to know. Let's talk.

Wait, what? No they don't. The author is an OpenBSD person and calls out several mitigations as clever and worthwhile.
