Here are some things that counter this:

https://users.ece.cmu.edu/~adrian/731-sp04/readings/Ptacek-N...: A paper that rocked the security industry at the time.

Tptacek also was cofounder of Matasano, now part of NCC; also cofounder of Latacora.

Also the co-author of https://cryptopals.com/, https://microcorruption.com/login.

The author of https://www.latacora.com/blog/2018/04/03/cryptographic-right..., https://sockpuppet.org/blog/2015/01/15/against-dnssec/, https://sockpuppet.org/stuff/dnssec-qa.html,

These are about what I call hard-core security, hardly insanely niche, and hardly lacking critical knowledge.
